I've been growing tired of anime for a while now and the only shows I've managed to keep up with lately are Ippo/Fighting Spirit on DVD (already seen it fansubbed though) and One Piece, but I picked up Steamboy since I'm an Otomo whore and watched it last night.
It really reminded me of why I got into anime in the first place. It was a great change of pace from Disney style plots, cartoons with musical numbers, or Pixar's someone getting lost storylines. Not to mention the fact that even in today's world of digital actors and CG sets, there's no way Steamboy could have been done in live action and been as convincing.
I have a few small gripes with it though. Whenever Ray and Scarlett were together I couldn't get over how much it was like Shinji & Asuka's characters/relationship from Evangelion and Ray himself could have used a little more depth as well. The last 45 minutes or so was a little bit high on the visual overload scale, so I could see how that turned people off, but I loved it.
The Collector's Editon box set is a bit of a rip though, if anyone is wondering what to get, get the normal edition. They didn't even translate the manga it comes with.
