Thanks to TCM I finally got around to seeing all the films in Satyajit Ray's "Apu Trilogy"; I'd only seen the first one, the incredible, sensitive, inside view of India that startled "art house" film aficionados, 1955's, Pather Panchali. After seeing the second and third one, Aparajito and The World of Apu I will just say these films are at the top of any list of great movies.
Once upon a time there were "art houses" whose golden age, I think, were between the late 50s and the mid-80s. It was a magical place to go to the movies, with adult fare, often set in foreign lands. Audiences at these theaters didn't usually talk and the cell phone hadn't been invented yet!
