I had watched Psycho years ago when trying to work my way through AFI's Top 100 via Netflix 1 DVD at a time plan. I thought the movie was excellent, but never watched any other Hitchcock's.
Last month, Netflix had some of his catalog available, so I watched Rear Window, Vertigo, and The Man Who Knew Too Much. I was pretty underwhelmed. Solid acting, a few interesting cinematic shots, but the plots were mediocre at best.
