I think this movie is great.  As a fan of the game, I knew I would like it.  And I'm not sure if most people understand, but it takes place before the game Resident Evil.  By the time it's the end of the movie with that final scene where Milla picks up the shotgun, it is the time of Resident Evil 2 (you'd have to see the movie to know what I mean).  I think some people thought this was suppose to be based on the first game for Sony Playstation, but it's not.
