I recently read all three books, very quickly and obsessively. While I did enjoy them, I found the present tense difficult at first. I don't mind first-person narrative, but something about using present tense irritates me!
I found the whole love triangle completely pointless. Not all stories need a romantic hook.
I really wanted to like Katniss, before I read the books, I was under the impression that she was meant to be a powerful female lead, but she wasn't that at all. She annoyed me most during Mockingjay, she took Peeta's predicament too much to heart. He was willing to sacrifice all he had for her, and she didn't seem to grasp the concept that his behaviour was not his fault.
As for the film... Well, I thought it was pretty rubbish. Parts were ok, I suppose, but there was too much silence. No one ever seemed to say anything? Maybe I would like in more during a second watch. I have the DVD so I might attempt it at some point.
The whole concept of the games really unsettled me. And as chilling as it is, I really do think that mankind is capable of watching children kill each other. It wasn't so long ago that people would gather to watch hangings and the like. Watching people fight to the death was entertainment a couple thousand (or so) years ago. Though, I think the worst part, in that respect, was the first couple of Districts actually wanting to be part of the games. But, I guess for the whole thing to work, there needed to be people who wanted to bring the 'glory' to their district, otherwise everyone would just hide in a bush - which is where I would be...
