I had to recommend this one for all of you anime fans out there. Actually, you don't have to be a fan of anime at all to enjoy this one.
The director Satoshi Kon continues in his wonderful style of blending science fiction and reality. This one is based on a science fiction novel by noted Japanese author Yasutaka Tsutui. When a program that allows individuals to explore their own dreams is pirated, the results are mind blowing.
If you liked the Matrix, you will appreciate this one. It is Rated R, however, for one particularly unsettling death scene, so don't watch it with the little ones..
