Overall I really liked it! There were details that bugged me, and I haven't re-read the first one in a while, but I think the transition from book to screen went well and I never found myself thinking about the actors while watching the movie. Though they chose a kinda annoying approach for the filming style that was rather shaky, I'm assuming to make you feel uncomfortable, and I think it was overused in the beginning. But it got better as it went on, and then they used it for the fighting scenes to keep it from crossing the line of violence over to R, so in that aspect it was a good choice. Just the beginning I didn't think needed the awkward camera work.
But yeah, overall I thought it was good! I also loved seeing the Capitol and the Capitol population's outfits, those were awesome. I can't wait to go see it again though XD
