Artigo bastante interessante
Actors Jensen Ackles and Jared Padalecki have natural and realistic sibling chemistry. Episodes like the comedic "Tall Tales" show off some classic sibling rivalry while visits from dad (played by "Grey's" dreamy Jeffrey Dean Morgan) usually bring the angst. Ultimately a relationship drama, creator Eric Kripke has confessed that if "Buffy's" theme was that high school is hell, "Supernatural" subscribes to the idea that family is hell.
With writers and producers from The X-Files and the Joss Whedon school of genre TV, "Supernatural" -- with genuine scares and comical one-liners -- deserves more than "Grey's Anatomy" and "CSI's" leftovers. ''
