I have never played any of the "Resident Evil" video games, but I understand this film is very faithful to the storyline -- specifically, it serves as a prequel to the first game (the end of the movie is apparently the beginning of the game). As a video game adaptation, this film is one of the most solid I've seen. Yet it takes most of its cues from the video game paradigm, and is constructed somewhat like the video game we all wish we could play.
