Created by Eric Kripke, "Supernatural" stars Jared Padalecki (Gilmore Girls) and Jensen Ackles (Dark Angel,Smallville) as Sam and Dean Winchester, brothers who were raised by their father to hunt paranormal predators and protect the innocent.

Though cut a little short (sixteen episodes) due to the Writers Guild Strike, season 4 builds and improves on the previous, offering action, comedy and horror.
