Sky High was ropey.
Try Azumi, Arahan, House of Flying Daggers, Hero or Zatoichi. Battle Royale, Casshern, anything with 'Beat' Takeshi in, Versus, Wild Zero and anything by Takeshii Miike are also worth looking at. Studio Ghibli has made some cracking animation recently.
Some wicked Korean stuff too: Old Boy, Save the Green Planet, Brotherhood, Joint Security Area, R-Point...
And that's just the crossover stuff that is easy to get hold of. There's a lot of chuff, but when they make a good one, it's usually very cool.
Play.com have got a big sale on, so I just blew loads on DVD's. Can't wait to see Time Slip/GI Samurai again And it was only a fiver
