Lately I've been watching Suits, the new tv show on USA, as well as White Collar, I've been giving Franklin and Bash a try on TNT but it definitely isn't nearly as good as Suits.
I also watch Weeds on a weekly basis although I'm almost certain that this will be its last season, and well it needs to be because It's getting pretty redundant if you ask me.
Prison Break was a great show
Breaking Bad on AMC - is an amazing show, newest season just started 2 weeks ago, and it already is awesome.
Californication - Showtime, hysterical
Entourage - HBO, great show
Dexter - Showtime, amazing show, great story and keeps you on the edge of your seat the whole time
And I agree with mcrawford, Sons of Anarchy is an awesome show, just caught up to the most current season on Netflix so I can't wait to see what happens next.
