Lisa Gastoni was excellent in this

Saw this today for the first time. Was partly what I expected, but also is a bit genre defying. I'm not sure I got all of it, some seemed a bit cryptic (the blonde doppleganger). But I thought Lisa Gastoni was really good in her part. Apparently this movie is best known because of the Ennio Morricone score. The final sequence in the ocean was really good the way the tone shifted to ominous. I'm not quite sure what all of it is supposed to mean, but I'll be thinking about this one for awhile.
