Psycho ****

It was on TCM at 1am and I wasn't tired and wanted to see it again. My favorite Hitchcock movie with tremendous performances from both Janet Leigh and Anthony Perkins. The score was also terrific itself. Does anyone know why Gus Van Sant remade this in 1998? I saw that version first but why remake this classic? IMO it was done completely right the first time, so what could you possibly do better the 2nd? If the answer is nothing, than why remake it? Some may say the same for the new King Kong but the special effects can be greatly improved in the 72 years since it's original release.
