The series' grim tone and overall look of a grimy world in perpetual need of dusting or wiping is a long way from Buffy the Vampire Slayer and closer to Japanese movies like The Grudge It's likely to startle you the way no show has since The X-Files. This creepy storytelling carries extra punch because the drama has an excellent, easy-to-root-for cast. A creepy, atmospheric, sometimes downright scary hour of TV. "Supernatural" is unlike anything else out there and should build a following among viewers who mythology and mystery adventure appreciate its combination of spooky Ackles and Padalecki are good-looking, yes, get to drive a '67 Chevy and will undoubtedly run into a lot of really hot women in peril, but "Supernatural" works. It's just serious enough, just hip enough and, as advertised, more scary than imagined. Of all the season's new dark-arts adventures, WB's aptly if generically named Supernatural may be the simplest and the scariest.... It wants nothing more than to frighten you -- and tonight, it does.
