Anyone who is open minded should consider watching this.
Not exactly a storyline driven movie, so if you have a short attention span don't bother. It's mostly a grouping of philosophies and theories on life, dreams, and death. Definately requires a few watchings to grasp some of the concepts here. On the flip side, some of it is seemingly meaningless rambling meant to sound impressive. However, the majority of the content is interesting and the unique animation style adds to the flavor.
