Shuichi Yô-ko ofthe Thieves Minamino
If you don't pay close attention to the twists and turns, you'll never understand what's happening. I realized close to the end about a few of the loose ends being tied up and had to watch it again to get the full experience of it all. But it ties itself together so well, the ending making the beginning so much less confusing than it was when you started. So you really do have to pay attention. But it's a very satisfying watch, if a little freaky. I highly recommend it. I'm going to buy it soon myself!

It was not the most creative or smartest movie but it was FAR from being the worst our dumbest. If you're on a supernatural, horror(ish) kick - you could do much worse.

One of the best newer movies I've seen has you on the edge of your seat in suspense, action, and mind bending. It's very well played and well made movie. Will not disappoint if you pay attention. This is definately a must watch and even rewatch if you will!
