I saw this about a year ago in Australia. It's a visual feast which makes it worth seeing, but the storytelling is incoherent and jumps around between major scenes, with the sudden introduction of key new characters and assumed knowledge (it's a well-known story in China).
The subtitles at the cinema I attended were hilarious. One character's name is Donkey Wang, which had the teenagers present (and me) laughing all the time. And there's a conversation where one character asks about an underground location "what's it like in there?" and the reply subtitle says "It's a spooky pandemonium."

Damn, that looks awesome. And I do love me some Tsui Hark. I'd have to hop a flight to Minneapolis if i want to see it on the big screen, though.
