Resident Evil 2 is my all time favourite game and these films were a massive let down. The fact they had the zombies disappear after they were killed and you leave the room because the makers of the film thought that was part of the game. Not knowing it was simply because the Playstation couldn't keep the dead zombies in memory so removed them when you moved out the room. There are so many mistakes in these films.

You are totally right when you say they need to stick to the source material.
