This is a story which, in other hands, could have simply been an all-female slasher movie, but Barbet Schroeder, who produced and directed it, has a mordant humor that pushes the material over the top. It is a slasher movie, and a little more.

Schroeder's refusal to choose moral sides gives the psychological confrontation between the women the kind of weird, mutually accepted form of diseased codependency that Claus and Sunny von Bulow shared in his previous film, Reversal of Fortune. In Single White Female, Schroeder leaves the subtext unresolved, but manages to strike a very raw nerve.

A clever, by-the-numbers gothic thriller. Single White Female is entertaining claptrap.

Single White Female is Mr. Schroeder's bid to compete in the mass market, and there's no reason he shouldn't succeed. The film is smooth, entertaining and believably sophisticated. It has far more sound psychological underpinnings than other movies of its type.

Even though Single White Female is more second-rate, knife-stabbing psycho drivel, it's no pain to sit through. It looks great, for one thing. It has two fabulous faces -- Bridget Fonda and Jennifer Jason Leigh. It's also funny, sexy, suspenseful and, yes, utterly stupid.
