Julianne Moore in the sort of supernatural/horror thriller that Julianne Moore occasionally stars in, about a "split personality" case that seems to be manifesting the personalities of dead people. If you're going for an actual horror movie, you don't cast Julianne Moore, but at the same time, she's a pretty good actor, and they usually cast other pretty good actors around here. In this case, the guy who plays the lead, who has to shift believably through maybe 10 different characters over the course of the film. Does pretty well. The whole thing would have been terrible with less of a cast but squeaks barely into "watchable" as it is.
