Leiji Matsumoto's famous Space Pirate Captain Harlock anime is on the web.
The year is 2977. Mankind has become complacent and stagnant. All work is done by machines, while humans spend all their time on entertainment. But when a mysterious invader from the stars catches Earth unawares, only the legendary space pirate Captain Harlock and the crew of the Arcadia have the will to stand against them.
Subbed, not dubbed, which is cool except that the translations are a bit iffy and have the characters saying things like, "Venture out!" And it's polluted with commercials, but not too many.
