It's amazing that a movie by a gifted director with many intriguing ideas about identity topped with grisly thriller and sexual elements can ultimately be rather dull. The first half sort of lumbers along and the second half, while better, manages to be rather predictable even though it goes places few movies ever have.
Pedro Almodovar's early films had ways of shocking audiences even though the subject was as straightforward as homosexuality or sex. But 'The Skin I Live In' has multiple elements sure to offend even the most seasoned film goer, yet it never gets off the operating table.
All the pieces seem in place and the structure is very tight [maybe too tight] but it doesn't soar like Almodovar's best.
Thinking about it a day later it seems that it surely must have been better than I thought. After all, the main conceit of the film is a whopper. [Think 'Vertigo' and 'Frankenstein' dropped into a blender] But the feeling I had as I sat in the theater watching it was rather underwhelming.
