The world as we know it, is no more. Tides have risen and drown the cities of mankind. The amphibious creations of a mad scientist, Professor Zorndyke (also the cause of the earth's condition) now inhabit the earth and lay siege on what's left of the human species. The only remaining military force must launch a daring strike to cripple the evil doctors forces.
Blue Sub 6 is one of my favorite animes of all time. The story is told expertly. All the characters feel real, and are developed exceptionally well. Even the "villains" get the same attention to detail. The seemingly mad, crazy and otherwise evil doctor who is the cause of everything is much more than just a "bad guy." You get to see what really led him to do what he did, and the ending dialogue between him and the protagonist is moving.
The animation is a mixed bag. The CG hasn't stood the test of time very well, and that's the only place i can doc it any points. All other animation is superb. The music is also a bit sketchy at times but for the most part it immerses the viewer into the world of Blue Sub 6.
I highly recommend this if you enjoy classics like Cowboy Bebop, Gundam Wing, and Dragon Ball Z.
