I watched two episodes from the reality TV show "30 Days." Episodes from Season 1 and 3 are available on Hulu.com. The show is produced by Morgan Spurlock, the same guy who did the well-known documentary "Supersize Me." The idea is that for 30 days, someone has to experience a life experience very different from his/her own or someone has to interact with people he/she disagrees with, for 30 days. Hence the name of the TV show.
I watched "Minimum Wage," an episode where Morgan and his fiancee try to work minimum wage to support themselves for 30 days, and also "Same Sex Parenting," an episode where a mom against gay parent adoption stays with a two dad family for 30 days.
I don't want to spoil anything, but I found the episodes well-done and enlightening. I often read about social injustice or minority discrimination but good documentary TV like this really drives home the emotions behind the issues.
