Meh.
Graphics were all right, style was great, violence was well executed, interactivity was beyond a PLAY button, and the humor was okay.
The one thing that killed my rating of this was sound! The voice--I'm sorry I don't have any suggestions in terms of fixing it :P--was pretty much what killed it. It got kind of annoying and had sort of a wooden feel to it, making the movie run kind of slow, figuratively. But even there you don't fail completely--nice choice of credits music, heh. :)
