Based on the mixed reviews that I found on the web, I wasn't expecting too much from Sorum, but I was very pleasantly surprised-although 'pleasant' isn't exactly the right word for this movie. I've included it in my unofficial list of overlooked masterpieces, including "The Third Page" by Zeki Demirkubuz, "Last Images of the Shipwreck" by Eliseo Subiela, and "Straight Through the Heart" by Doris Dörrie.
Sorum is not for everyone. The emphasis is on character development rather than shocks or special effects. The characters are not particularly likable, although I related to all of them in one way or another. The pacing is deliberate-until the end, when the various subplots snap into place to form the big picture.
Like the unfortunate author in the movie who is writing a novel about the events occurring around him, I found the ending very satisfying. You have to pay attention, though, particularly during a scene when the main character is having a haircut in a barbershop. (Unfortunately, this is when the white subtitles appear over a light background, which makes them hard to read.) When the movie ended, I was confused, but as I thought about it, the ending became clear and I started laughing, just the author before he got punched.
