I don't think this franchise is good movie material. I remember playing the games and not caring about the story at all. There is no character development or interesting plot, just shooting people and everyone acting eccentric and telling potty jokes. The movie had little substance to go off of.
That's not a diss to the game. It's fine that the game is like that, but they should have recognized it would produce pitfalls for a movie adaptation.
The cast is a whole other issue. Why would they go with Cate blanchet for this?
