Identity is a whodunnit thriller that follows hotel guests getting murdered one by one. The movie is thrilling, suspenseful, and even scary in parts, and it had the potential to be one of the most inventive whodunnit murder mystery movies of the 21st century. But the quality of a great murder mystery absolutely hangs in the balance of its ending, and Identity, unfortunately, has the laziest ending possible.

It was all in Ed's imagination, and as he deals from dissociative identity disorder, all the killings represented Ed killing off his different personalities. Some movies can pull this off if it's done creatively, such as Fight Club or Shutter Island, but Identity couldn't have been any lazier.
