This movie was very, very disturbing. I can't help but noting that I would never voluntarily see this movie again, and even that I wish I hadn't seen it the first time.
On the other hand, I am forced to admit that it was a very good movie. The fertility imagery was a little TOO heavy-handed for my liking; I felt like shrieking "OKAY, I GET IT ALREADY!!!" about twenty minutes into the movie. But I suppose it all related to the theme, so it was okay.
The Otik-creature is also very disturbing, but the food scenes are probably the worst. I remember the food from my stay in St. Petersburg, and this movie was fairly accurate. Don't see it if you've recently eaten, or plan to eat at any time in the future. Ugh!
I think the movie would be classified as a dark comedy if it were American. As such it was extremely funny; the dialogue is quite witty and the acting is good. But the whole thing was just... disturbing.
Beware of violence; there are a few very bloody, graphic scenes. The nudity is nonsexual, so it's really not a problem even for prudish Americans like me.
