Well not that I'd advocate pirating shows that aren't on over here but I've heard bits about these:
Alphas (first season was so-so but the second is much better apparently)
True Blood
Breaking Bad
Burn Notice (probably Marmite but what I've seen I like)
Teen Wolf (probably not to everyone's taste it's a bit teen-y at times but second series has been excellent going by reviews)
House of Lies
Yes do this - in both of these the first half of the first season is laying background and introducing characters for all the stuff that comes afterI started watching Justified and Sons of Anarchy but got bored of both. Lasted 4 or 5 episodes of SOA and about 8 of Justified. Maybe I should have given them more time.
me and the mrs are hooked on Leverage.
if you get FX channel they have just started showing them all again from season1.
What time/day?
