Roswell, Alias, Lost, Supernatural, Bones.

Last season of Lost wasn't as good as the others, but I could watch it over and over again, rofl.
Alias... I started watching it with my friend a couple of months ago and I'm hooked!

I CAN'T WAIT for the season 6 of Supernatural! Seriously. I LOVE that show.
And I've been obsessed with Roswell since december, I don't know really know why in december, but I wish I had season one and two on dvd right now!
Bones is just so funny... and dramatic. The end of season 3 completely leaved me speechless. I need to see season 4 and 5.
Otherwise I love : Buffy the Vampire Slayer (best tv show ever), Angel, One Tree Hill, Moonlight, Prison Break...
