It wasn't the first novel, nor the first film about the subject, but most of us got familiar with this type of thriller (and murderer)
Both in print and on screen the subject became boring very soon
I don't know how many crime writers came up with their own serial killer novel, and none of them was decent (even Harris' sequels were poor); as far as the films are concerned: they were as poor as most novels. Maybe Copycat was the best of the lot. It wasn't good, but at least it wasn't pretentious and the actors did a proper job (they weren't pretending to be in a Greek tragedy). The worst was probably the Manhunter remake with Neeson.
Hopefully we're through with this nonsense
