I watched Alfred Hitchcock's Vertigo last night. The more Hitchcock movies I watch, the harder it becomes for me to appreciate current movies. What he did with camera angles and lighting is just amazing. It puts most current special effects efforts to shame. Hitchcock added so much more to his movies, with so much less.
Without getting into spoilers, I will just say that Jimmy Stewart played one of creepiest movie characters ever. And the ending was amazing, I never saw it coming.
