Corrected entry: Quill wouldn't recognise Gamora at the end as they hadn't met before, reason being is because she travelled forward in time with Thanos before meeting Quill and stayed there. Regardless of Cap replacing the stones.
Corrected entry: When Natasha first finds Clint in Japan, and tells them there might be a way, he looks straight at her and says "Don't." He's looking her in the face in that shot, but when it cuts to her face and she asks "don't what?" you can see his face in the foreground but looking down at the ground in front of him. When it cuts back to him again, saying "don't give me hope" he's suddenly looking back up at her again. (00:57:09)
Corrected entry: Loki escapes with the Tesseract in 2012 and didn't go back with Thor so the events in the other Thor films didn't happen as Loki was a key character in them and Thanos couldn't get that stone, regardless of Cap putting the stones back at the end.
Corrected entry: Thanos should have noticed there were no stones in the Gauntlet before his final snap attempt. When he knocks Iron-Man off he pulls his hand back, and as he adjusts the glove, he looks at the back of it. He sees it fully in the wide and he can at least see the back of the thumb in the close-up. (02:29:50)
Corrected entry: When Peter Parker returns to school, he is seen reuniting with Ned. If everyone returned 5 years after the snap then Ned would be 5 years older and no longer in high school. If Ned had been dusted he wouldn't have known Peter was also dusted so he wouldn't have been so relieved and happy to see Peter.
Corrected entry: The Wasp showing up at the end battle makes no sense. She didn't even know what was going on when they disappeared and came back, and Dr. Strange didn't know where or even who she was, so nobody would think about bringing her there. It's also too paradoxical for Dr. Strange to know she was needed there because he saw the future, simply because there was only 1 chance.
Corrected entry: When Thor and Rocket are sneaking past Loki's cell, Loki is playing with his object but in Thor: The Dark World, that was almost the same time Algrim became Kurse and caused the prison break. Plus Jane Foster never woke up, because she didn't sleep in in that sequence in the original film, and when Thor is talking with his mother, there's no sign of a battle going on outside. (01:09:20 - 01:29:45)
Corrected entry: One of the big sources of tension in the heist is the fact that they supposedly have a limited number of Pym particles, as stated by Scott Lang. So after the test run they only have enough for everyone to take one round trip through time. Cap and Tony use their return supply to go to 1970, which is why they needed to steal more particles to get back. However, Ant-Man's shrinking tech is also based on the Pym particles, and his shrinking suit seems to work without restriction in 2012. They also have enough to both shrink the Benetar in 2023 and re-grow it in 2014. So either Scott is mistaken about how many Pym particles he has, or he is lying about them. And before someone says they calculated the number of particles it would take for the shrinking during the mission before assigning them to the team members, Scott discusses the limited supply before they had any plan of what they were going to do in the past.
Corrected entry: In the battle scene with Thanos the Scarlet Witch is able to destroy some of the double bladed weapon of Thanos and it is knocked to the ground showing a large semi circle portion of one of the blades is missing on it. Later Thanos throws the double bladed weapon at the van to destroy the Quantum Tunnel and it shows the weapon as now completely intact as it hurls through the air towards the back of the van.
Corrected entry: When Tony pulls up to the lab (after the initial time travel attempt), he is driving an Audi e-tron. We hear it driving and the engine revs as he pulls up. However, Audi's e-tron line is fully electric. Therefore you wouldn't hear the car's engine.
