Corrected entry: About 30 minutes in, Kirby & Jill are watching Shaun of the Dead. Kirby says as such when Olivia calls from her driveway. Before going into her house, Olivia hangs up and after a moment gets a call from Jill, after pausing Shaun of the Dead, pretending to be Ghostface. Then, the real Ghostface calls. During his conversation with Kirby, he asks how Shaun of the Dead is. How did he know that? It was only discussed before Olivia entered her house and the movie was on pause after she entered her room. Since Ghostface was in Olivia's closet, he wouldn't have been able to know what movie was playing by seeing it.
Corrected entry: In the scene where Jenny is trying to crawl under the garage door, the door is shut on her and we hear a sound that is supposed to be her bones breaking. If her back or spine were broken, she wouldn't have been able to crawl forward and fight the killer (and if her back was broken, she would have immediately passed out). It should be the garage door closing sound we hear, not a "bones breaking" sound.
Correction: Since we do not know for sure the extent of her injury, it is impossible to tell whether she'd still be able to fight the killer or not. People have also been known to be fully conscious for a short time after having their backs broken.
Corrected entry: [Bit of a spoiler alert so don't' read any further if you haven't seen the movie yet.] At the end of the movie Sheriff Dewey tells the person who is the killer that Sidney is in critical condition and may or may not live but a few seconds later we see Sidney awake and alert and with enough strength to fight off the killer once again.
Correction: Anger and fear can be more than enough to gather enough strength to fight your way out of a difficult situation regardless of how much of a critical condition you are in.
True, but you can't have a lot of anger and fear if you are unconscious. The way the situation was presented, was that the doctors weren't even sure she was going to make it. It is part of the suspension of disbelief in movies to be very lenient with injuries and their implications, but this is really pushing it.
Corrected entry: If you have watched the rest of the Scream films you will know that Dewey was stabbed in the back in the first film which caused him to have a very noticeable limp during the rest of the original trilogy. In this film he walks completely normally. Even with modern day treatments he'd still have a little limp.
Correction: Whether or not a person can recover from a noticeable limp depends on the specific injury. All we know is that Dewey suffered a knife wound. Even a specialist in neurology would be incapable of determining the extent of the injury based on that little information. And this ignores that there are plenty of stories of "miraculous" recoveries, despite everything medical experts believe to be true.
The original Williamson script (which was revised anyway) does address it; "His limp is nearly nonexistent. Years of physical therapy", but as the entry correctly says, we don't have even a little limp. In the fifth Scream he is limping again. I am sure you could argue that he let himself go and his physical shape got worse and the limp relapsed, however there are so many inconsistencies throughout the saga about his unrealistic limp and lame arm that I don't think this should be corrected.
Corrected entry: WARNING: Lots of spoilers! Throughout the entire movie, but mostly in the end, it's made apparent how much smaller Jill is than Sydney and the rest of the adult cast (watch her height and size compared to others, especially when she is laying next to Sydney at Kirby's house and the hospital). Charlie is shown to be the same height as Jill, most noticeable at Kirby's house when they kiss. However, in the scene where the cops are killed outside of Jill's house, the killer is taller than the cop. Not possible seeing as Jill and Charlie are both kinda small.
Correction: I wondered about this too, but then it occurred to me that Jill could simply have worn platform shoes whilst in the costume to make herself appear taller. This would help towards nobody suspecting her because, as you said, she is much smaller than Sydney.
Corrected entry: In the end, approx 15 min before end the guy with the head camera goes to the balcony with bottle of light brown liquid but on the balcony he is drinking from the small (pocket size) bottle.
Correction: I just watched this scene and the bottle remains the same size throughout, it never changes.
Corrected entry: Towards the end of the film when Kirby and Sidney are about to go to the basement, Kirby says something about her router being smashed, a few moments later it shows her iPhone screen and she is connected to WiFi.
Correction: Perfectly plausible there's another nearby wifi network her phone automatically picked up.
Correction: Spoiler alert! Its revealed at the end that Charlie and Jill are the killers. Since Jill is with Kirby, its obviously Charlie calling. Jill could have texted or previously told Charlie that's what they were going to be doing later to scare Kirby a little bit more.
