I liked the books fine. Decent escapist fare. I have been pleasantly surprised by how good the first movie was, even with the limitations of converting a book to film. They hit the right high points, downplayed the violence just fine while still having enough to add a feeling of real danger and loss, and didn't leave out or change anything crucial, like they did in Ender's Game, which was a travesty of epic proportions. I am looking forward to the second movie.
FWIW, I thought all 3 books were consistently the same quality. I liked the underlying story and I thought they pulled it off well. The only gripe I had was that in choosing to stick to the 3rd person narrative, it is limited to how Katniss sees the story, and since she is in essence confused through much of what is going on it serves to confuse the reader a bit as well. The author doesn't give us quite enough observational data to deduce what is going on, in other words, as usually is done in 3rd person, so the reader can generally know more than the main character by figuring it out when the main character doesn't figure it out and it isn't explained outright. They would have done well to use a limited omniscient narrative for parts just to help fill in blanks for the reader, when in the end the author had to jump through some minorly awkward hoops to fill out the story for us after the fact. Otherwise, I thought the last book was a fine read. The author even managed to pull off a reasonably satisfying ending contrary to what the whole story generally built as the desired outcome.
