Saw this a couple days ago in BG with demonfire. I liked it quite a bit, and you will too if the idea of hot chicks in somewhat revealing clothing battling enormous samurai statues, clockwork Nazi zombies, dragons, etc. excites you. :3
Many will no doubt compare it unfavorably to Inception, but I still have yet to see it (no lectures; I know I have to), so I cannot make that comparison and thus enjoy it for what it is. MovieBob really liked it, hailing it as deep and meaningful beyond the flashy surface T&A, and while I’ll agree that it gives you something to think about, and doesn’t go where you’d expect, it’s sure not as deep as he makes it out to be. It’s still worth seeing.
