We don't have TV, but we do play Netflix movies over the winter on the computer. We took down the desktop and whole TV/sound system this past summer, and wow is it nice! You don't realize how much room all that stuff takes up til you pack it up and send it to the garage. So we're on the lowest Netflix plan that you can get and still do the watch instantly unlimited (8.99/month). I love documentaries too, since my hubby isn't going to pick up Nutrition and Physical Degeneration, but he'll gladly sit through Food, Inc with me. And I can knit or nurse the baby while watching a movie. Not so much with reading :)
Here are some documentaries that we found interesting lately, first link to Amazon if you don't have Netflix, second to Netflix so you can add it if you want. I'll note that a lot of them touch on evolution; we believe in young earth creation. Evolution doesn't make up a huge part of any of them, though.

Omnivore's Dilemma (review coming eventually, I really enjoyed this book) would be my preferred sustainable solution.
