I saw this yesterday as well, and I thought the key to enjoying it would be to go in with uber low expectations. Despite that, I actually found myself enjoying the movie!!
The storyline while typically fanstasy like, was highly orginal (at least I thought it was), and the world and environment was well built with a good background. It felt like they thought a lot about it, and it definitely shows.
I have only two complaints:
While the movie had a tremendous cast, some of the other actors though left a lot to be desired.
The pace for the movie at times lagged sometimes (and by this I mean, events didn't seem to be advancing the plot measurably) and a few plot events seemed rather contrived. It felt like one of those moments where had I read the books I'd know what the movie was referring to
Anyway, this part felt like a good solid foundation for the story. The sequel I presume will really carry the plot.
