would be the Sopranos for me

great channel though, also love The Wire, Game of Thrones, True Detective (the first season, not seen the 2nd), Boardwalk Empire... and there's some supposedly great shows that I haven't got around to seeing yet (Oz, Six Feet Under, Deadwood)

and their comedy / light-hearted shows are great too (Girls, Looking, Getting On, Curb Your Enthusiasm, Flight of the Conchords)
