The producers of The CW's Supernatural have yet to think of a monster, demon, or ghoul they didn't like enough to pit against siblings Sam (Jared Padalecki) and Dean (Jensen Ackles). In the clever "Roadkill," though, the boys encounter an inventive villain all the show's own.
Sam and Dean, driving down a deserted road, come across Molly (Tricia Helfer), a panicked and bloody woman screaming for help. As their luck would have it, their new gal-pal is being chased by madman/farmer/ghost Jonah Greeley (Winston Rekert), an evil spirit who murders one person every year, on the same day and at the same time.
Backed by Greeley's tragic and grim mythology, "Roadkill" is Supernatural at its creepiest and, most importantly, original.
