Alfred Hitchcock was a pure genius. His movie gave us the paranoia that directors today try and match. His film Pyscho gave birth to movies like Friday the 13th, Nightmare on Elm Street and Halloween. Yes Pyscho was the birth of the slasher film. Low budget but incredibly horrifying audiences used to be locked in the theatre so they would sit through the whole movie. At the time Hitchcock showed us the voyeurism techinque (Like coming in the window) And it shocked and appalled audiences. Now although horror today is trying to match Hitchcock. I believe he is and will always remain the best horror director.
