Hitchcock, come back to us now, and make a movie like that and add a clever ending. What is wrong with you people falling for crap like "eXistence" or "Se7en" or "Fight Club" or "Memento". Of course you can write mystery thrillers but unless you come up with an explanation at the end it is not even satisfying, it is annoying! So come back, Alfred... Macaulay J. Connor
