Good balance without being ridiculous This movie is excellent as far as content goes. Many things that were unexplained in the original are dealt with, and not in a way that seems ridiculous. All that happens in part IV could conceivably have happened, so that's good.
Anthony Perkins does a wonderful job of recapturing the essence of the disturbed Norman Bates, and Henry Thomas is very believable as young Norman. His performance completely illustrates the up-bringing of Norman by his unstable mother.
Good supplement to the original, I thought.
