"I prefer the films that put their audience to sleep in the theater. I think those films are kind enough to allow you a nice nap and not leave you disturbed when you leave the theater. Some films have made me doze off in the theater, but the same films have made me stay up at night, wake up thinking about them in the morning, and keep on thinking about them for weeks. Those are the kinds of films I like." — Abbas Kiarostami, 1997.
Here are some films streaming on The Criterion Channel that will allow you a nice nap.
