It's 'Supernatural'

There aren't many shows that could largely reinvent themselves in their third seasons and come out on top. That would require almost, ahem, "Supernatural" intervention.

And yet The CW's Thursday-night (8 p.m., Ch. 30) action/horror/thriller/comedy has done just that. It's better than ever.

For those of you who haven't checked the series out, "Supernatural" began as the story of brothers Sam (Jared Padalecki) and Dean Winchester (Jensen Ackles), whose mother was killed by a demon when they were very young. Their father, John (Jeffrey Dean Morgan), seeking revenge, became a skilled demon hunter and raised his sons to follow in his footsteps.

When the series debuted in the fall of 2005, the elder Winchester was missing and his sons were looking for him, battling various demons and legends out of folktales along the way.

Much to their credit, creator/executive producer Eric Kripke and his team didn't let that drag on forever. In the two-parter that aired as the Season 2 finale back in May, the Winchesters hunted down and killed the Yellow-Eyed Demon who started all of this.

John, who had traded his life for Dean's earlier in the season, returned in ghostly form to wrap up his story line as well. But while this marked a major turning point for "Supernatural," it didn't by any means leave the series with nowhere to go.

Before the Yellow-Eyed Demon could be destroyed, he opened a gate to hell (in Wyoming, of all places) and unleashed scores of demons who are now free to pursue their evil ways on Earth. So Sam and Dean set out to hunt them down and send them back to hell.

Not only that, but Sam was actually killed at the end of last season, so Dean made a deal with a demon that gave Sam back his life — but at the cost of his own. Dean has one year to live, then he's headed for hell, too.

So the boys are hunting demons, and Sam is determined to find a way to void the deal and save Dean.

Don't let the fact that there's a lot of history behind "Supernatural" scare you away. If there were some kind of award for best opening synopsis by a prime-time series, this show would win hands down.

In the space of a minute or so, each episode opens with a series of flashbacks that establish the show's mythology all the way back to the beginning so you can tune in at any time and catch up. Heck, if there's something from a specific episode in the show's past that applies to the current episode, that's in there, too.
