I watched "Little Chenier: A Cajun Story" last night. A very good look at cajun bayou life. No fake over the top action, just real people in real situations, and pretty authentic. Filming on this wrapped less than a month before the entire area was destroyed by Hurricane Rita, and the end credits have some staggering before-and-after pictures. It is believed that this is the only footage of the Little Chenier area that exists.
BTW: I love this thread as I'm new to Netflix as of last week...with the suggestions given here it'll be a while before I watch regular TV.
