I watched a movie last night called Spirited Away, its basically an Japanese animated cartoon (not sure if its classed as Anime), but it is very beautifully done, Disney should take a look put it that way. It also won the Oscar in 2002 for the best animated feature.
It have one of the weirdest storylines i have ever seen, about a family that come across this strange tunnel near their new home, walk through and end up in a bath house for the spirits (yeah - i told you) but i thouroughly enjoyed it.
I'd give it an 8/10 at least.

You do need to disengage any rational thought for it though.
