Don't worry about the Japanese only; it's silent with no intertitles. It does help to read a bit about it before you watch it though to clarify the plot. Here, for example: http://www.midnighteye.com/features/silentfilm_pt1.shtml

Very highly recommend this with the Alloy Orchestra score. Unsure how the other scores (or lack thereof) are, but the Alloy one is one of the effective scores I've heard for any movie.

I don't really get the movie. Surrealistic films are just not my genre, notice that I dislike more than I like and when silent with no text to follow the plot closer, even less interesting. Not to say it was all bad, there some really nice visuals uesd and the portrayal of madness through dance and imagery was neat. So I did enjoy parts of it but it could keep my interested or vested all the way through. I will need to read through the link that Book Of Sand provided to understand the plot more.
