Watch Supernatural Online - Full Episodes

"Supernatural" is a show that revolves around a pair of Hunters named Sam and Dean Winchester. Sam and Dean are brothers, and Dean is the older brother. The series kicked off September 2005 and was supposed to end at the end of the fifth season. The end of the series didn't have anything to do with bad ratings, but it had everything to do with the fact that the show's creator, Eric Kripke, had planned for the show to have a predetermined ending with no loose ends.

However, it was announced in February 2010 that the show would be renewed for a sixth season. The seventh season ended May 2012 and the eighth is set to start airing in September 2012. Along with the Winchesters, who ride around in Dean's pride and joy, a 1967 Chevrolet Impala, the cast includes a host of demons, angels, Hunters and the boy's father-figure, lore-master and fellow Hunter, Bobby Singer.

Their mother was a Hunter first, though this fact wasn't known until later in the series. Her death and the circumstances surrounding it caused John to take up the Hunter career. Dean gladly followed in his footsteps while Sam attempted to eschew the family business and lead a regular life. That, however, didn't work out. The first few seasons follow Sam and Dean as they track down Yellow Eyes, the Demon that killed their mother and marked Sam as an infant, and try to find the Colt, a gun made by Samuel Colt that was made to kill demons.

As the series progresses, the ultimate battle between Good and Evil is introduced. Demons have run amok from the very beginning, but angels were introduced in the fourth season with an angel named Castiel. He rescues Dean from hell, and Crowley, a middle-management demon, is also introduced. His cavalier attitude makes him a very likable and amusing character, despite his being on the "Evil" side.

The original series finale at the end of the fifth season saw the Apocalypse thwarted and Sam sent to Hell with Lucifer and the Archangel Michael. Since then, Sam's been brought back and the brothers have had quite a ride. Sam carted Lucifer around in his head for nearly two seasons, Dean realized a normal life was beyond him, Castiel went from helpful to taking God's place and unleashing the Leviathan on the world to becoming a pacifist.

Despite the seemingly serious themes of the series, there is a lot of humor such as Dean's love affair with fast food and 80s rock ballads, Castiel's naivety, Sam's out-of-place seriousness and the Prophet. There are allusions to the huge, devoted fan community, an anime series and a graphic novel that revolve around the series as well.

Supernatural continues to be a humorous, watchable series with well-developed characters and an entertaining story arc.
