I really enjoy One Tree Hill - havent gotten a chance to see the new 8th season yet, waiting for the DVDs
Also like Ghost Whisperer, though I haven't seen any full seasons yet as my channels seem to be random..
I actually finally watch Vampire Diaries all 2 seasons out so far and enjoyed that fully!
Roswell was an old one but I have all 3 season of DVDs so I watch those a lot, super good .. Hereos.. at one point
Others I watch here and there are House, Simpsons, Greys Anatomy, Criminal Minds, The Mentalist, and this other show I don't know what it is called but its like a S.W.A.T show but better.
EDIT! Just looked it up as I am watching it now =P FLASHPOINT!!!!
