The answer of course is very little, it is an incredible roller-coaster of a film.
However I do have some problems with it and here they are:
I would have given the wolf slightly shinier teeth.
There could have been an extra step at the bottom of this staircase. I would have also made her left boob slightly bigger.
Amy Acker is a respectable actor, can we please cover up her legs, I expect this slutty display to be rectified for the DVD release.
This does not happen once, in the film. So if you are looking for a film featuring rubik’s cube style shacks you are in for a world of disappointment.
