The main problems with these films are that they bare virtually no resmblance to the games. When we do meet actual characters from the games in the films, they are generally crow-barred into the stories purely so the film makers can say, "There you go gamers; Jill Valentine, Chris and Claire Redfield and Carlos!!! Happy now!!". Their addition to the films add nothing more.
Also there is very little sense of dread from the zombie/mutant threat as Alice (cue Roy "Chubby" Brown song) dispatches them without breaking a sweat/nail/hair etc.
There seems no logic or real plot behind the films anymore other than to get a super-powered (is there any other variety?) Ms Jovovich running about in a skimpy outfit, killing stuff with impunity.
