106 minutes so close to the sacred 100 minute mark, but I still watched it at 1.5x because I've generally had bad luck with anime -- it creeps me out ("Spirited Away" disturbed me so much that I nearly vomited) ... this one was a little better in the sense that it didn't *completely* give me the heebie-jeebies ... but still, it's strange and sort of awful when you really think about it.
The animation is amazing, it's incredibly dense and complex -- and the main story is kind of interesting (the kids switching places in time-space), but there's something about animation from Japan ("anime") that just seems off ... the mysticism, the dreaminess, the hyper-reality ... I just have a nagging feeling that there are some real sickos behind it.
You'll love it if you love anime ... could give it a shot if you've never seen one before ... but it's a red for the general audience.
