Full Metal Panic! - Season 2

The Second Raid is a return to form for the series and an improvement on pretty much every aspect. Only 13 episodes, it feels tighter than the first season, rarely deviating from telling its story. The art and animation are markedly superior to that of the first run, much more fluid and stylistically pleasing. Part of this is thanks to the addition of two female antagonists, creepily emotionless and very adept at combat. The show is also more mature, more willing to show violence and sexuality than before. Sousuke and Kaname still aren't really together, but there's noticeable advancement in their relationship as they act closer to actual human beings around each other. His attitude gets a little annoying later on, but he comes back around eventually.

The story introduces a new, more-or-less insane villain and evil plot against Mithril, the military organization Sousuke works for. The new characters are interesting and they continue to keep the story exciting and tense. The stuff with Kaname is also handled very well, as her influence on him and vice versa becomes clear and she's the focus of one of the most tense anime episodes I've ever seen. The action scenes are cool and the climax is fitting, though I have to wonder if this is the end. There's multiple novels left to adapt and the whole story's still not really over, but it's been over two years since this was produced and there's still no word of them going back to work on it. I hope they aren't finish, because I think it's a tale that deserves to be completely animated.
