Banking on the prestige of Monster’s Ball, director Marc Foster goes for broke in this hallucinatory free-for-all about a suicidal artist (Ryan Gosling), his psychiatrist (Ewan McGregor), and the psychiatrist’s lover (Naomi Watts), another suicidal artist who used to be his patient. Trying to solve various mysteries, the shrink soon becomes crazier than the other two. If this is a psychological thriller, I stopped being thrilled once I realized anything could happen; if it’s a mystery, the denouement raises more questions than it answers. With its flashy, pretentious visual effects, this is really a 98-minute dream sequencethough it’s worth recalling that the most effective dream sequences tend to be only a few minutes long. David Benioff (The 25th Hour) wrote the script; with Bob Hoskins and Janeane Garofalo. (JR)
