Have you seen Oz? Its another HBO series, think it was around the same time as the Sopranos first was.
Six Feet Under The Sopranos Oz Dead Like Me(the first two seasons that were on ShoTime.) Warehouse 13 Fringe I've been thinking of starting Son's of Anarchy but I'm not sure about that one.
The Wire House Deadwood Law & Order SVU Band of Brothers Peep Show Green Wing Ricky Gervais Show for a brief laugh (brief as in episodes, not humour)
Scrubs and House. My 2 favourite things ever on tv after Blackadder...and a string of quite a few other british comedies.
Thanks for all the response guys and girls, we started watching the wire but a friend suggested chuck and offered us season 1 and 2 so were now working through that.. have to say "Capitan Awesome" is well just awesome! lol With everyone suggesting fringe I should probably say were already addicted to that and were gutted when the season ended Again thanks for all the suggestions, got the page bookmarked for when we burn though Chuck and The wire
