I'm from Denmark, so I dunno if you have the same shows, but I like Spartacus, The Walking Dead, Orange Is the New Black (a bit slow, but loads of lesbian activities, if you're into that), Bad Samaritans (Funy as hell but only 5 episodes or so, boohoo!), Breaking Bad, Modern Family and Shameless US.
- The Walking Dead - Lost - Burn Notice - Family Guy - Doctor Who - Prison Break - Charmed - Supernatural (Early seasons only! Later it gets boring) - That 70's Show - Warehouse 13 - Being Human (US) - Lie To Me - White Collar
Sherlock was definitely a great find! Rescue Me if you didn't watch when it was on. All the obvious ones: Walking Dead, Doctor Who, Arrested Development. The Riches was only on for 2 seasons but was a great mix of comedy & drama, and the series finale didn't leave you hanging at all. If you like crime dramas I recently discovered Crossing Jordan, which I never watched when it was on, and there are 6 seasons so it'll keep you busy.

Heartland is THE best and I would also recommend Alaska State Troopers, which is basically a show that shows what cops do, and there are quite some epic fight scenes in there as well, if you're into that.
Doctor who,Sherlock,and drop dead diva....drop dead diva i find really underrated because its about a girl who dies goes to heaven hits the "return button" and gets put in someone elses body and is working by her former fiancee and has to struggle with her seeing him going through missing her while she cannot tell him that she is her.....its a amazing plot.
Firefly is an incredible show. It got cancelled after one season, but they revived it with a movie following the season that may be even better than the series. Both the movie and the series are on netflix instant.
