I don't really watch a lot of TV, but I liked how Bryan Cranston played Hal in Malcom in the middle and this character seemed to be so different so it gave it a try and I fell in love with Breaking Bad. It's hard to imagine a show better than this but as I said, I'm not expert when it comes to TV shows.
I thought Walking Dead was good but Breaking Bad makes WD look like something MTV would air.
I've heard good things about Sopranos, House of Cards, Game of Thrones, so I guess I'll try them in the future
