Big Bang was introduced to me by my English teacher a few years ago.To be honest,I was infatuated with Sheldon,as soon as I found him humorous.Besides,i really adore Queen B in Gossip Girl .In brief,which American drama do you like best?
Shameless US is the best American drama I have ever seen.
I don´t know if these are dramas but I like some series like: 90210, doctor house, once upon a time, CSI, America´s next top model, and others !
The Big Bang Theory isn't a drama. It's a sitcom (situational comedy), a genre that is defined by extensive humor, episodic plots, and a confined setting (i.e. the "situation"). Dramas are far more serious in their nature, and they have a focus on season-long storylines. Gossip Girl could be considered a teen drama, but BBT definitely isn't.
With that said, my favorite drama is probably either Breaking Bad or Supernatural.
I like One Tree Hill and Castle best, but I also like series like Big Bang.
