Without offending people, I must be so bold as to suggest if you don't like Hitchcock, you don't like film/cinema (at least as an art-form, vs movies as an entertainment vehicle).
I would also recommend Oldboy, but be forewarned, the film scores rather high on the disturbing scale.
Since I speak Korean, I watch some Korean movies (not a lot though). Old Boy is not only disturbing, but the ending has a better twist than Sixth Sense, No Way Out and Dead Again. I could even throw Primal Fear in there I suppose.
My jaw literally dropped open at the end. What a crazy/disturbing ending. I heard that Quentin Tarantino was going to remake it in the States. We'll see.
