Can anyone recommend some good submarine-themed anime and provide some info on the anime (ie. brief synopsis)?
I've only seen 2 submarine-themed anime and both were OVAs. I've seen Submarine 707r and Blue Sub No.6
I just recently watched a 2 episode OVA called Submarine 707r. It's based on a really old manga from the 1970's by the same name. The animation was pretty impressive and smooth and there was plenty of action. The basic plot was solid (a mysterious organisation called the USR, Undersea Silent Revolution, is waging war with the rest of the world) but having only 2 one-hour episodes, this OVA fails to explain a lot of things. The orign of the USR wasn't explained and there was very very little character development. To be honest, it's more like a taster of the manga than an animated version of the manga, which is a shame because I reckon it would have a pretty entertaining show. I'd still recommend people to watch it though.
Blue Sub No.6 is a pretty well known OVA and was one of the first shows to use CG paired with traditional animation. It looks stunning visually and had a solid story. Definately worth watching.
Anyways any recommendations and info would be much appreciated.
