The Big Bang Theory

I try to avoid sitcoms and drama series, but I have to admit that I'm getting addicted to the named sitcom. Reasons: (1) it is smart, it makes you think, (2) lead characters are played excellently: Sheldon is great in more than one way, Penny is sexy and sociable, Leonard is an epitome of a good guy, the other two guys are also peculiar, (3) the dialogues are great, and I am big fan of dialogues ever since I first watched Pulp Fiction.
