Ahh... you liked it
That's just a guess. This in no way, shape or form, should be construed by the good people at 20th Century Fox as my review of the film.
Mathematically, I could hate the visuals, follow the logic like a rabid bloodhound, love the direction and be completely unmoved by the script, and still have responded "half right". Or any other combination thereof that breaks things down in such a 50/50 manner.
There were more reviewers at the screening I was in, and I think there was a definite consensus among them, but, hard to say. Especially when you're not supposed to talk about it.
