This is Weird, even for the Greek Weird Wave standards...
The first thing to notice is that this is one of the most gorgeous filmed movies I've seen, each frame is like a painting of a master.
I cannot say that I fully understand it but I challenge anyone to try such a thing on first viewing (or 10 views). The review and partial theory that I've read from Jonathan White on this site seems to go closer to my own impressions, and since he writes much better than me better leave it like this.
Now I need to find time for a second viewing.
