I just saw this on Bloody-Disgusting. It looks pretty good. I stopped the trailer after about 30 seconds and put it on my list.
I still haven't seen Hunger Games. The bit when the teacher showed up was funny to me because I remember a teacher that probably wasn't a bad guy. But a group of us messed with him for some reason. I don't think I did anything but I hung around those other kids. And I remember being questioned about what exactly happened. I can't remember it that clearly anymore because it was somewhere between maybe 4th or 5th grade.
I watched this yesterday. Got to say I was disappointed, really annoying characters, pretty bad acting, bad script and I didn't care who lived or died. There was some nice gore but unfortunately a lot was masked by the horrible red lights on the suits. See it if you have nothing else to do, I wouldn't make a special effort to see it.
