Plot hole: While in the battle arena the vials with the purple R substance in them become broken, letting the gas out. All so the Pokémon seem to go crazy from it but Pikachu doesn't.
Factual error: Towards the end of the movie when Superman and Henshaw are fighting on the Watch Tower in space, Lois hits the sun shades to lower them so that direct sunlight can hit Superman and power him up. This is out in space with no atmosphere to filter the sunlight. The reason the blockers were there was for this reason, to keep the harmful unfiltered sun light from hitting people on the ship through the windows. However, she is able to stand there in the direct light after it's done and kiss and hold Superman without being hurt or burned by the intense direct unfiltered sunlight or its radiation.Quantom X
Plot hole: The girl in the basement of the JPL building comes across a locked door with a combination lock. She hits a few buttons and the door opens. There was no way she could know the combination. She is at JPL for the first time in her life and everybody - except her three friends she came with - is dead. (01:23:20)toroscan
Continuity mistake: During the sign-up for the app at the beginning the girl says "I want to be Sarah." Look at her hair; mostly in front of her left shoulder, just a couple locks on the right side of her face. At the cut, hair behind the left shoulder and a bigger right bang. Camera angles and hairstyles switch again back and forth. (00:02:30)Sammo
