Excellent. Not much more to say.

I only have a little trouble understanding the initial setup: a society, frightened by its youth’s violence (I guess it’s still a bit of science-fiction as far as Japan is concerned, but it would perfectly apply to France’s suburbs) decides to send each year a ninth grade class on a desert island for the students to kill each other. And what I don’t get is… what’s the point? I mean, what’s the motivation for a government to vote that? The script and directing are so efficient that you very quickly dismiss the question, but since the movie seems to mean to have some kind of political, or philosophical, or somethingical, purpose, it’s a bit important. Is there something I’m missing? When I read the movie synopsis, I expected they’d send the worst or more dangerous students, to get rid of them. Instead, it’s a whole class, selected at random, and there even aren’t cameras on the site. So what use can it be, except either enticing youngsters to be even more rebellious, or giving the opportunity for an excellent, though unrealistic, script?
