As far as Twilight goes - I read it. The first book was alright, and they went downhill from there. The fourth was the most disappointing because it felt like Meyer was rushed to put it out and, in all honesty, there isn't much literary value to it at all.
I think the Hunger Games has a lot of promise. From the trailer and interviews, the casting seems pretty good. A lot of people were concerned about Josh Hutcherson as Peeta, but from what I've seen so far I think he'll be great. I'm really excited to see the movie and I hope they do well with the adaptation from the books to the movies. From what I've heard, it's got the making to be the next big series.
