When it comes to TV - aside from evening news - this is one the few things I really bother to watch. I get my dose of Lost and suchs from Internet anyway.
It's a reality show by the guy who made Super Size Me and, actually, 30 Days follows the documentry's structure pretty closely. But instead of fast food the show tackles other subjects in similar manner such as living with minimun wage. 30 Days can be a corny but most often it's just really interesting and entertaining. Apparently they are going to make a third season but I haven't even seen the second season as a whole yet.
