Psycho then. One of Hitchcock's finest gets the sequel treatment in the 80s, the slasher era. Time to feel worried, but you shouldn't be as this is the most surprising film I've seen in that, unlike most sequels that merely re-tell the original, this has the brilliant twist that you are watching Norman Bates thinking "Is he doing it? Is he being set up? Why is this film so clever?" You will watch this film feeling glad that it is so good and like the first film, it has another big reveal-all speech at the end but this time THEY GET IT WRONG! Fantastic stuff.
