As another season of Dexter came to an end last night on Showtime, the cable network teased the beginning of an all new series. Immediately following the season finale of Dexter, the first 20 minutes of the pilot for Showtime’s new series Shameless premiered. If you don’t watch Dexter, or you just plain missed the sneak peek, don’t worry, because Showtime has released the entire lengthy tease of the new series online for your viewing pleasure. Adapted from a popular British show of the same name, Shameless chronicles the exploits of the Gallaghers, a family of degenerates, made up of William H. Macy, Joan Cusack and Emmy Rossum, who seem to be constantly breaking laws and moral codes just to get by. Check out the sneak peek after the jump!
