I think that it has potential to be a great action film. I'm not expecting this to be a fantastic film, but it should be a fun action film. I don't expect this game to be focussed on pleasing existing CV fans than making a movie for the mainstream to enjoy.
I think its kinda rediculous to hope that this film gets cancelled, also. What harm is a movie, true or not to source material, going to do to you, or even the game series in general?
