Oh my god. This anime is fucking awesome.
I liked the movie. I've only seen up to episode 19 of the series though.
Seriously, watch this.
I'm slowly working my way through this (just got up to 16, where Cobra joins a killer baseball league).
This show's got everything, loads of action, a lovable goofball but badass hero, tons of hot women, over-the-top villains, great music and animation that still looks really good today.
Illuminati, the group that scans Riki-Oh, translated the first volume of the manga but dropped it. A real shame, but the show seems to follow it well enough.
Can't wait to see the new Cobra.
