Other mistake: After realising they can track the mother box, Batman says they have to go back to his base to use one of his satellites to track it, and they all do so. Which completely ignores the fact that Cyborg could easily access the satellite feed directly using his abilities and display it to the others on any nearby screen in Star Labs.
Suggested correction: Just because he had many options available to him, does not mean that the option which he chose was wrong.
Other mistake: Despite being a deadly marksman (only a few minutes earlier in the movie he stopped a bullet directed at him shooting it off the air), Bloodsport snipes several times at the huge kaiju featuring a massive eye in the central part of its body, and never once hits it. (01:51:45)
Other mistake: When Cole gets in to drive, he puts it in gear to drive, then starts driving in reverse. (00:22:50)
Other mistake: When the assassin is trapped inside the airlock with Tiger, she chokes him, and he collapses. The assassin then begins to walk back to the door to the ship, but just as she is about to open the door, Tiger sneaks up behind her and opens the airlock. There is no way she wouldn't have heard Tiger approaching her. The space was very confined and would have heard his footsteps whilst walking up to her. (01:52:05)
Other mistake: While Snake Eyes is fighting at the beginning of the film, the other guy throws him to a block of concrete. Snake hits on his head and should be dead by then or at least seriously injured.
Other mistake: Hero drove his car through a line of armored men and crashed onto rocks along a cement wall. Two days later when he returned to his car with gasoline (where one of his bombs exploded by the car), there was smoke and dust blowing through the air all around yet views of his car showed it was perfectly clean - shiny black.
