I watch so many different shows, I'm not sure I can name a favourite. LOVE Buffy the Vampire Slayer and Alias! I also watch Merlin, Nikita, Doctor Who, Dollhouse, CSI: NY, True Blood, Moonlight, Heroes, 24, I could just go on. I have also recently become addicted to The X Files.
As per sitcoms, The Big Bang Theory, Corner Gas, I Love Lucy (which is very true), Friends, Mike & Molly, and select seasons of Two and a Half Men. I watch some select science shows, though it depends what is on. Liked Lonely Planet/Pilot Guides during its run. BBC's Natural History Collection is a definite.
I must agree that Johnny Depp is an AMAZING actor. He is excellent in the Pirates of the Caribbean movies; of which there is a fourth coming out, I believe. I also quite like him as the Mad Hatter. Really, really love Audrey Hepburn though; Breakfast at Tiffany's and Roman Holiday are my two favourites.
