I liked Rope.
Rope is probably my favorite.

I guess I'll say Rear Window since it hasn't been mentioned yet.
I also have a huge soft spot for
Rear Window, due to multiple viewings during my childhood.

But there's generally something about mid/late 50's-era (or somewhere between
Strangers on a Train and
Psycho) Hitchcock that bugs me; That big studio sheen, the constant fragile blondes...As for
Vertigo, and leaving aside the visuals, I always found it a little too melodramatic(!)
There are many great colour Hitchcock films, but I think the black and white American films are his best looking.
I tend to find them more enjoyable too. There's an efficient tightness to them that those later films can lack; From earlier movies like
Shadow of a Doubt or
Saboteur, or even less well-known titles like
Stage Fright, to
Strangers on a Train and
Psycho.
I think the problems that I have with the '50s Hitchcock get worse with the '60s (post-Psycho) Hitchcock.
As for the '70s...
