Supernatural season six could potentially be the most interesting season to date. If you're not familiar with the series, it centres around two brothers, Sam and Dean Winchester who hunt demons, monsters, ghouls, ghosts and pretty much all things supernatural. You see what they did there?

Sam and Dean were raised to be hunters by their father, who was also a hunter. When season one started, the boy's father was missing and Sam was at college after turning his back on the family business, so to speak, and trying to live a life of normality when his girlfriend is killed by a demon.

Not just any demon. It's a demon who also visited Sam when he was a baby and killed the boy's mother. This brought Sam and Dean back together and the trail of finding their father also became the hunt for that demon.

As the story progresses it is revealed that Sam isn't quite human and has been tainted with demon blood. The hunt and final showdown with this demon takes us up to the end of season three. Along the way we are introduced to other hunters, most notably Bobby, a grouchy old friend of their father, and Ellen and her daughter, Jo. The season ends with Dean dragged to Hell after making a deal with a demon.

Season four had a new twist. We'd seen all manner of bad guys, vampires, werewolves, vengeful spirits and demons. We were then introduced to some new good guys, angels. Now, when I say good guys, it really isn't that simple.

The season started with Dean being dragged out of Hell and soon reunited with Sam, who had been on a downward spiral, becoming addicted to demon blood to make himself stronger. They were soon joined by Castiel, an angel, who revealed the demons have a plan: to release Lucifer himself from imprisonment and let him lay waste to Heaven and Earth. The season ended with the cage open and Lucifer out.

Season five was going to be Supernatural's last season. The season started and you, the viewer, really didn't know how it was going to end and who would be left standing, and potentially, nobody could have been.

Sam was revealed to be a vessel, a body that can host an angel, and a vessel for not just any angel, but Lucifer himself. Dean, in turn, was revealed to be a vessel for Michael, God's strongest angel.

The season ended with Sam leaping back into the cage with Lucifer trapped inside him. The final scene was Dean seeking solace in a normal life with a former love, Lisa, and her child. As they settle down together, Sam is revealed outside watching...

And so we come to season six. Supernatural as a show has always been very good. The two leads, Jensen Ackles and Jared Padalecki are accomplished in the roles they play and the series has always carried itself with a wry sense of humour.

The show's creator, Eric Kripke, left the show at the end of season five, handing over the reins to Sera Gamble. It is said that Kripke will still be involved with the show, but Gamble will be handling the day to day running of the show. That means, with someone new at the helm, the show almost has a blank slate to do anything it wants.

Come September 24th, I'm looking forward to finding out.
