Anything by Home Box Office is always top notch.
My jailbroken Applebox has frozen so I can't watch the last 2 episodes remaining of GofT until it's fixed.
HBO's Deadwood for sheer aural assault with swear words Ian McShane plays Sheriff Al Swearingen... absolutely marvellous character.
Google "The number of ducks (sic) in Deadwood"
A few clips on youTube will give you a flavour.
