Hitchcock's masterpiece is considered one of the greatest horror films of all time, and it's definitely one of my favorites, too. Reading the essay collection Kolker edited, you realize how the film lends itself to various interpretations. The music essay I had to abandon, because it had so much music theory that I might as well have been reading a Hebrew Bible or something. Some of the viewpoints were repeated throughout several essays, but each was still good and perceptive in its own way.
Sometimes film (and literary) analysis reaches a bit too deep for my own taste and might try to point out something that isn't really there, but this collection was mostly saved from that. I felt like watching Psycho again, and other Hitchcock films will also get my attention in an entirely different way. Examined superficially, Hitchcock might seem mere entertainment, but in reality the films are extremely polished entities both visually and thematically. An amazing mixture of auteurism and mainstream suspense. Although he was mentioned to have considered his films funny, so maybe there was more twinkle in his eye than you would think. I have Hitchcock's biography waiting, and I expect it to elaborate on that aspect.
