Big Bang Theory is one of those scapegoat shows that smart people have a stock "it sucks" opinion about. It's a very good light sitcom as far as light sitcoms go and easily holds its own with shows like How I Met Your Mother.
To clarify, I like him because he doesn't have a TV _and_ he doesn't care about pop culture. I don't either, so I don't have a specific opinion on The Big Bang Theory.
