I continuously fell asleep while watching this movie. The actors performances are superb (on the other hand Naomi Watts and Ewan McGregor are a guarantee of success) but the viewer is supposed all the time to figure out what's happening. It's an experimental film putting the audience to the test all the time, a puzzle much more then a thriller motion picture. The plot (a shrink trying to prevent his patient from committing suicide) is not standard but not even unconventional, the setting, as well as the special effects, make the situations cryptic and weird. The problem is that many times things need to be deciphered.
