Giving this a whole two stars is kind of a stretch. It's arty and pretentious. I nodded off for long periods. When I do that during other movies, I sometimes feel obligated to re-watch the DVD to at least fill in the gaps; I didn't feel that obligation here.
Anyway: it's based on the Dostoyevsky story of the same title. (Considered by most critics to not be one of his better efforts.) Jesse Eisenberg plays nebbish Simon, working at a soul-draining job in some unspecified bureaucracy, disrespected and ignored by everyone.
Things change when James shows up. He's everything Simon is not: charismatic, interesting, popular. But here's the thing: James and Simon look exactly alike. (My keen eye discerned that this was primarily due to both roles being played by Jesse Eisenberg.) The two develop a relationship, but it's an unhealthy one.
The setting is dark and surrealistic, with absurdist and stilted dialogue, and unbelievable characters. Basically, a 93-minute nightmare for Simon, but I don't think he wakes up. Or, if he did, I missed it.
