Just got back from seeing this. Anyone else seen it yet?
I really enjoyed it. I only had one small problem with it and that was when some of the Tributes died early on, because I didn't know anything about them, I really didn't care that much (Apart from the fact that they were kids and shouldn't die like that). I went with someone who has read the book and they said that in the book you did get to know all of the Tributes more. In the movie, you pretty much know nothing about almost all of the Tributes.
Apart from that, it was a pretty awesome movie and I would recommend it to anyone. Everyone put in a good performance and was well cast I thought. It looked great and was really well paced. No really stand out moments or sequences. It was just a good solid all round movie from start to finish.
Spoiler:Maybe the Muttations were a bit dodgy looking for some people, but not in it long enough to really make a difference. I didn't mind them. Anything is better than the wolves in the Twilight movies!
