This is not one of the shows that are filled with mystery, intrigue and a complex plot. It does not come anywhere close to the anime masterpieces like Neon Genesis Evangelion in any aspect. However, if it's fast paced action that you crave, this is the show for you.

I won't spoil much of the plot here. The basic premise is about a bunch of teenagers fighting for survival against huge humanoid monsters in a post-apocalyptic setting. The main characters are well fleshed out. There is plenty of gore, and the show does not shy away from killing off major characters on a whim.

The production values are marvelous, and the quality animation makes it a feast for the eyes.The opening themes are catchy and among the better ones in anime.

This is the only anime series apart from Death Note that made futile all my attempts to resist watching one episode after the other.

In conclusion, this is a show best watched on a marathon session on a lazy weekend.
