Just finished rereading Mockingjay. And yep, it's just about as depressing as I remembered from the first time through. At least this time I was able to slow down a little, since last time I was practically skimming - having to go back and reread several bits I missed the first time - because I was absolutely positive that Collins was going to kill off Peeta. Almost as certain as I was that Jacqueline Carey was going to kill off Joscelin midway through Kushiel's Avatar. I have trust issues.
But holy cow I can't wait for these movies.
ETA: However, I do intend on killing the next reporter/blogger/moron who insists on comparing them to Twilight. Because arrrrrgghhhh.
