For the record…True Blood is the shit, but you have to watch it from the very beginning.
Entourage is good too…you can pretty much pick up any season of it and start watching and jump right into the characters.
But all jokes aside the best thing you could probably start watching if you want to just rent something and run straight through it…
AVATAR: THE LAST AIRBENDER
That cartoon is better than EVERYTHING on television…I shit you not.
