I consider myself as reasonably intelligent, but this movie went totally beyond me! Thanks to the titles of the various parts (chapters) I at least could gather that reincarnation should be the main theme, so somehow all the goings on had to be related to that. But to be honest, I nowhere in this movie came across even one single thing that seemed in any way to refer to reincarnation. When I force myself to look at it with a positive, or at least a well-meaning attitude, I could say that it's about dreams: either the psychological meaning of (recurrent) dreams, like forming a bridge to repressed memories from childhood; or even, in a more surrealistic way, comparing life itself to a dream. But reincarnation???
There are definitely interesting scenes, also visually, like the party where all these weird guests were gathered, or the masked woman singing on the rooftop, or the almost gothic scene of the surgical operation that took place in a deserted medieval tower. But unfortunately there were many more totally unfathomable scenes and actions that seemed to go nowhere, like the floating man, or the doubling of the persona of Rory (who or what Rory was stayed unclear anyway), or the "Help...!"-cries that came out of several different phones. Were these things maybe meant to be supernatural? Or was the whole movie one big dream??
It all went (I'm sorry to say) down the same dreary and pretentious drain. The pace is extremely slow, the dialogues are awkward, and the acting is unimpressive, except for Thomas Mann, but he couldn't save this project on his own. John Malkovich sure didn't help, with his (as so often) blatant over-acting.
