Interesting film 15 Rear Window

So many Hitchcock films to choose from. I saw them all pretty much in my twenties when I used to go to triple bills at the Everyman cinema in Hampstead. I considered Spellbound, Rope and Frenzy but went for Rear Window which I have always had an affection for.  Whats your fave? or all they all overrated in your opinion?
