Generally speaking this film has two strikes against it before you even sit down to watch it.
1) It's a film based on a video game franchise. With the random exception here and there films based on video games are not great, good or even decent. They're bad and horrible.
2) It's a film directed by Uwe Boll. Boll is one of those directors that people(gamers) love to hate and with good reason. He's turned several games into below average films.
However, back on topic of Blood Rayne 2, I have not seen this film so I'm not going to bash it or praise it directly. Instead I'll do this, below is a link to the comments section on the Internet Movie Database. The film currently has a 4.9/10 score after 1,738 votes.
