I watched my BD of The Hunger Games this evening and enjoyed it. After I saw the film in the theater, I gave it only 7 Stars out of10. That was primarily because there was so much shaky cam and so many quick cuts I got frustrated. Tonight, though, that mostly didn't bother me and I was able to improve on the most grievous examples. For about two minutes after the games started, with the kids running for the goodies and fighting each other for their lives, there was so much of it, I went back and watched those two minutes a frame at a time. Because of how bad it was in real time, looking at it frame by frame was fun. New information was provided every time I moved on. As a result of finally being able to see what happened at that critical juncture, I have raised my rating of the movie to 8 Stars out of 10.
The 7.1 HD audio, especially the LFE, was sensational. The surround effects could not have been better and the scenes with heavy bass were a revelation. For example, early in the film, before the games, when the hoover craft flew over the woods where Katniss and Gale were hunting there was a lot of shaky cam. I hardly noticed it, though, because the LFE had already started to make my viewing room shake.

I was fairly underwhelmed by the two hours of extras, most of which involved the director, some of the actors, and some executives puffing the film. It was shot in HD though, so it wasn't a complete loss.
All in all I enjoyed The Hunger Games more on BD than I had in the theater and recommend it.
