A quick read, with clear sparse prose that suits the POV character very well. I loved Katniss -- if you don't, you might not like this book, since it's all in her head, but I loved her enormously. A lot of interesting society-building, cool secondary characters, and a really interesting exploration of what it means to be on display at all times and to actively use that fact. (I loved that Katniss actively used it, and that so did plenty of others; a lot of times, you see protagonists who deal with being on display with angsting and self-destructive tantrums, instead of treating it like a tool that saturates the world and will be used by you or by others against you.)
Not sure if I'll like the second and third books as well, since I've heard some spoilers about things that tend to annoy me, but I plan to read them and see.
