Research on mad men
 A Review on the guardian quotes to back up what the audience feels about the season 5 episode 11
http://www.theguardian.com/tv-and-radio/tvandradioblog/2012/may/29/mad-men-episode-11         The person who wrote the review feels strongly towards characters and has their own view on what the characters do and feel in certain situations an example of this is the person has wrote about Pete Campbell and his choice to propose such a thing to Joan."I have not felt a loathing so visceral for a TV character in a long time, if ever. It wasn't just the depravity of his actions; his decision to actively pursue the idea of Joan selling her body so to improve SCDP's chances with Jaguar."
This proves its not a main stream programme because it lets the audience think and become active towards each of the characters an have their own view on their actions they perform this is what the AMC is trying to achieve by trying to make the series of mad man character driven instead of plot driven like LOST.
