Well, I watched the movie over Easter Weekend. I meant to post earlier, but I agree with PBJ a lot. I felt the whole hunger element was gone. The funny thing is during the games, they were showing her eat...a lot, but they never bothered showing much passage of time. They show probably 6 meals take place during the games, but only visually show you that maybe 4 days have past. My wife who never read the book was confused why she was always going around eating all day. In the movie, it seems like she finds water within 20 minutes of the games starting.
I think character development was cut short as well, you had no connection to why Rue was a big deal, it feels like they knew each other for one afternoon. When you get to the brutality and killing, it was done well and kept pace. They thankfully cut back at the cheesy teen romance. Gale's anger against the capitol was completely gone, so he is just a dope gazing off into the sunset. Haymitch was one dimensional, which is a shame because woody did a great job, they just didn't give him any film time. They didn't even bother chopping off Peeta bread's leg, but I guess that wasn't a critical thing to do for the movie.
District 12 was a shaky fail, you had no sense of how Katniss had to trade to survive and put her name in for rations of grain. They just shook the camera for ten minutes while she ran around. Her thunder thighs and the well-fed nature of everyone in the district takes away any notion of hunger being a key element. They didn't even seem poor when townsfolk are watching the games on a couch on their 60" flat-panel tv screens.
But even after all my complaints, it wasn't necessarily a bad film. It was just not a masterfully done film. Kinda like one of the frustrating Harry Potter films. You just end up cringing when they miss the mark or chop out parts that were critical to the story, but you will still watch it again.
