Plot hole: Obviously, tooth fairies are real, in this movie at least. During the movie, Derek has to retrieve each child's tooth and put money under the pillow. He's paged as soon as the kid loses the tooth, since he often has to wait till the kid goes to bed before intervening, and he is required to do it as soon as possible. But parents are doing the same, and at one point in the movie Derek actually stops a dad that just did the swap and extorts the tooth from him. That of course creates a parodox: the majority of parents in the world apparently have been subjected for centuries to the freak occurrence of finding already under their pillows mysterious money and their children's baby teeth missing as they go do the deed themselves. You can't have both the fairy and the parent do the same task.
Suggested correction: This is part of the suspension of disbelief for holiday movies like this. Doing this means you would have to apply the exact same logic to every Christmas movie depicting Santa as real leaving presents for children when the parents would just see gifts appear they didn't leave behind.
I thought the same, but the thing is, it's all left to the imagination, for instance you can assume there's some "magic" that makes the parents forget everything and just assume they bought the gifts themselves even if they did not. If they meet Santa, it's considered a special deal, and its consequences are not shown, so it all stops here. Not here, here there are specific magic devices (a magic dust of forgetfulness exactly to erase memory of what happened, for instance) that in this encounter is not used by The Rock. So this movie is awfully specific about the interaction between the magical agents and whatnot, to the point that they need to erase their traces and not be spotted, but those rules don't make internal sense. Had they said nothing about it, I would have just assumed it was like every Santa movie as you mentioned, where it is not presented by the movie itself as an issue with contradictory solutions.
Plot hole: The Chinese army displays a great variety of (often anachronistic) weapons and they spent considerable resources arming and reinforcing the Great Wall to challenge the beasts who have been plaguing their land every 60 years for thousands of years. but despite having records of magnets being effective against them, with magnets being well known to them for centuries (early magnetic compasses were available in the IV century BC, and the movie is set in the XI century) they made no use of that at all.
Plot hole: The Mummy would not know where to crash the plane in England to retrieve the dagger from the Abbey as this was placed there thousands of years after her imprisonment. If she did know it was there using her powers she would know that the stone was missing, but she didn't.
Suggested correction: Ahmanet did know where to crash the plane. She had the ability of sensing the dagger. Jenny even points out to Nick that Ahmanet knew where to find it. Ahmanet's powers are not fully explained but, since she could sense the dagger, she probably thought the stone was still with it but didn't know until she tried to stab Nick. Later, when the Prodigium agents find the stone, Ahmanet could not only sense it but, told Jenny it was found.
Plot hole: The world depicted features magic, an evil overlord who 2,000 years before tried to conquer the world, and several races. Despite these HUGE differences with our world, everything turns out of the same as our world, with nations as they are now, and a casual mention of the Alamo and "Mexicans still getting shit" for it. So our current history has not been altered a single bit by wizards, dragons and super-strong races roaming the Earth. Fine. In this ungodly implausible context, orcs live with humans in cities that mirror ours; humans and elves don't trust them, but still they live in towns with them, they go to schools, run businesses, half of the NFL is formed by orcs. Even the movie Shrek exists! And yet, at the end of the movie Nick Jakoby becomes the first Orkish police officer in the USA! There is just no way a society like this, mirroring closely our own and with orcs that existed as long as humans did, can exist with no orc ever been part of law enforcement.
Plot hole: When Sully and Mike are talking in the toilets, during Boo and Sully's Hide and Seek game, Boo comes running in screaming and upset because she's just seen Randall, and he's not too far behind since all three can hear him talking offscreen to the CDA before entering the toilets, but how did Boo get to Sully faster than Randall without him seeing her, and how did Randall not hear her screams since they're all in the changing rooms which have an echo?
Plot hole: When the chipmunks finally release their first song, there is a montage showing the chipmunks rising musical success. In one shot we see a marquee promoting "The Chipmunks Premiere CD Release", and on it is a picture of the chipmunks in the clothes Dave has made them (note Alvin in his 'A' jumper.) However, Dave doesn't actually make the chipmunks these clothes until further on in the film. (00:41:50)
Plot hole: Near the end of the movie, when Mr Potts finds out that he's going to be rich (Mr Scrumptious wants to buy his invention) and he rushes out to his car to go see Truly, he meets her en route and she's got her hair in an really elaborate style and has changed. But there is no way she could have possibly got to her house, found out that her father had gone to see Mr Potts to buy his invention, changed her outfit, done her hair like that and gone out to see Mr Potts in the short amount of time between Mr Potts and his children dropping her off, and Mr Potts and her meeting at the pond.
Plot hole: At the end, Jake utilizes multiple Loops to reach September 4th, 1943, the date from which Miss Peregrine's children impossibly entered another Loop set in the winter at the beginning of 2016. The closest date prior to this was in 1942, from when Jake waits for September 4th 1943 to arrive. However, having entered a Loop in 1942, he would have been unable to reach 1943 because he'd be stuck living the same day in 1942 over and over.
Suggested correction: Is it possible he left the loop while in 1942? The movie doesn't directly address that idea.
It does address this, actually. He'd have reentered the true time period upon exiting the loop. I suppose he could have prevented the local ymbryne who created the loop from resetting it, but if he did, he'd have doomed all those peculiars in the process. Not something Jake would do.
Several of the ymbrynes had been captured. It is very likely that the one who created that loop had been too, so the loop would have closed, and he could've lived in that time period.
Plot hole: The wolves seem to conveniently make an appearance to further the story, only to disappear in other parts. They are there for Belle's dad at the beginning and Belle when she tries to escape the castle initially. When Belle's dad leaves the castle after Belle takes his place and when Belle is freed to save her dad, they are not there.
Plot hole: The Ghostbusters go underground to search for the slime using a map. Even excusing their initial dumb decision to try to dig a hole in the middle of Manhattan when they could have taken that route to begin with, there's no excuse why after their acquittal they never went looking for that river of slime until Vigo burns their lab; they spent weeks studying small samples of the thing but never tried to reach again the source of the infestation to monitor it, which is absurd. (01:00:00)
Suggested correction: The Ghostbusters know from Ray's initial journey down the hole that the river of slime is in the old pneumatic transit system. They are busy re-opening their business and will eventually go back to the river, but that mission gained more urgency once they linked the river to Vigo. Also, they know that the river has been there for years if not decades, and therefore realise that returning to explore it can wait a few weeks.
Plot hole: The famous line "There can be only one" is uttered in every Highlander film. At the end of the original, Connor obtained the prize by killing the Kurgan and being the last one. However, in this film and others, you find out that there are still others around, such as Duncan, the woman who was Duncan's girlfriend in Endgame, the other immortals following Jacob in Endgame, and the ones that showed up in The Source. So, why did Connor obtain the prize? He still wasn't the last one.
Plot hole: Kahn's death makes no sense. In the film, Rayden explains that the dragon tattoos flee one's body upon the person dying. And yet, Kahn is still alive and not even close to death when his tattoo flees. (Which is what kills him, since it rips him open when it flees.) It's like they couldn't figure out how to kill him in the script, so he's just spontaneously is killed by his tattoo, even though it violates the rules the film set up.
Plot hole: If the Medjai are supposed to be the guardians against Imhotep and sworn to make sure he never comes back to life then why weren't they in possession of the key that opened everything in the first place?
Suggested correction: Because it got lost in the centuries that passed. It's possible they don't even know every step on how the mummy can return.
Plot hole: Why would Madison take a bath in steaming hot water? The ocean water is warm or cold depending on the area of the ocean. So, it makes no sense as to why she does this.
