Awesome series. Some people accuse it of getting stale and repetitive but I never found that to be the case. A great mixture of dark humour, unusual art style (of which studio SHAFT is well known for) and social commentary - some of it only really applies to Japanese/Otaku culture but there are still a lot of things that ring true no matter where you live.
This show is completely unrealistic in terms of dangers you would face in a tank. But if you can ignore that it is quite good fun.
Season 3 was glorious. Too bad a huge part of the story was skipped in order to animate this.
Quite an underrated show.
Masterpiece
