Vertigo ★★★★★

It's not my favorite Hitchcock film, but it's hard to argue with people who call it his best. Bear in mind there's a good many Hitchcock films I haven't seen yet -- hence the project I'm going to soon begin, where I'll spend the year watching all 52 of his surviving features (including this one again) -- but it's difficult to imagine a film more exquisitely thought out and constructed than this one.
