Battle Royale by Koushun Takami.
Brilliant from start to finish---I dunno how so many novels manage to be better than their movies, and with the translation from Japanese, I really expected this to be one of the sole exceptions, but I see I was horribly, impossibly wrong.
This is a novel with a living, breathing soul. With few exceptions, the characters are extremely realistic, highly detailed, and many are sympathetic. It's gorey, gritty, and blunt, but at the same time, I see it as a very positive, uplifting work, if only because as stories about the dark side of fascism go, it's worth keeping in mind that this one takes place in an alternate reality present as opposed to a grimdark future. I find that makes considerable difference in the content.
I noticed a thing about the writing style that reminded me, of all things, the Haruhi novels, and I'm wondering if it's an accepted part of Japanese literature: namely, idiosyncratic parenthetical asides. In many cases, it felt like the author was randomly inserting a joke into the work, and the interview with Mr. Takami at the end of the translation I read does little to sway my opinion on the matter---he's a very funny seeming guy.
Characters exercised poor trigger discipline which would have drove me nuts if they weren't largely innocent 14-15 year old kids. If bullet proof vests worked nearly as well as the one in the book did, then there'd be less war, or possibly somehow more gross and violent wars, depending on how bitter you're feeling today.
The homosexual character kind of irritated me because of how flaming he was, but he wasn't the only character like that, so I later revised my opinion and decided instead of a mincing fairy stereotype, he was actually just a narcissist. Also, I had to keep in mind that I was reading a book from 1999 Japan---knowing only what I can glean from anime and other media I digest, I have no way of knowing if this was actually a progressive portrayal of a homosexual---merely having him be in the book and vaguely competent, albeit not Kiriyama competent) Speaking of the book's time being Japan 1999 (actually, the book takes place in 1997, I believe) it was really jarring to me, even though I knew it was a fascist country, that only like, two people had cell phones. In Japan. Then I remembered "OH YEAH. This was fifteen years ago."
Lastly, Chapter 70 is the most ludicrously out of place thing I've ever read before. And the worst part is I HAVE KNOWN OR KNOWN OF GIRLS EXACTLY LIKE THAT, so it still somehow manages to be quite realistic. Just one of the more amazing tension breaking chapters ever---I have to think good ol' Takami wrote that one with a big ol' shit-eating grin. I know I would have, had I the brilliance to do it first.
