my review =)

The season focuses on protagonists Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles) as they track down Azazel, the demon responsible for the deaths of their mother Mary and father John. They attempt to discover the demon's plan for Sam and other psychic children—young adults who were visited by Azazel as infants and given abilities, and whose mothers often then died in a fire. During their travels, they use their father's journal to help them carry on the family business—saving people and hunting supernatural creatures.
