I know I already reviewed the first part of the show, but now I’m going to finish it out ^^
About halfway through series 4 it begins to become less of a show where you do not have to watch in order and more of a story based theme. Each season had it’s own overarching plot, with the Winchester brothers fighting some evil thing or another. Here is the breakdown season to season, if you don’t worry about spoilers.
Season 1: The Winchester brothers hunt for their missing father and on the way fight ghosts, demons and monsters. They are also seeking out the demon who killed their mother.
Season 2: Sam and Dean’s father gives his life to bring Dean back from the brink of death. Now Sam and Dean must hunt down the yellow eyed demon to avenge their mother and father. Sam fears his growing powers as some kind of connection to the demon who fed him blood as a baby and wishes only to prove he is not going to become evil.
Season 3: Dean trades his soul for Sam’s life and is given one year to live before he is dragged down into hell. Dean is glad to finally be at the end of his line, but he is pulled along by Sam to try to break the deal and find out who the demon is that holds his contract.
Season 4: Dean is back from Hell suddenly and without explanation. While he was gone for only 4 months the time span in hell equals 40 years of violent and horrific tortures. He tries to forget, but Sam wants to know. Meanwhile Sam has a secret relationship with Ruby, the demon who appears to be their new ally. Dean also meets Castiel, the angel who pulled him out of hell. The brothers try to stop Lilith, the first demon, who is trying to break the seals and set Lucifer free.
Season 5: Sam, intoxicated on the demon blood, accidentally breaks Lucifer from his cage, walking into a trap Ruby set for him. He tries to make amends while the brothers avoid demons and angels who wish them to allow the archangel Michael to possess Dean and Lucifer to possess Sam in order to bring the apocalypse into full swing.
Season 6: Dean’s been living a normal life for a year- a beautiful girlfriend and her son who he loves. But suddenly Sam reappears, not trapped in Lucifer’s cage after all. One trick though- his soul is still trapped and is being tortured. Dean gets it back into his body, but a barrier has been put up between the memories of hell that will kill him. On top of all this is Castiel, leading the angels in civil war, and Crowley, the new King of Hell who seems to be looking for a gateway to Purgatory and the souls locked inside.
The latter half of the series shows a huge improvement in the acting. The Winchesters look less pretty-boy and a bit more rugged. Sam is less puppy dog and a bit tougher. More and more we see the comedic side of the Winchesters, especially in Series 6. We also see more of Bobby, the Brother’s father-figure and the guy they go to for help.
Episodes are directed by a range of people, and one episode in Season 6 is directed by series star Jensen Ackles himself. There is no instance where it stands out that the directing is bad, so I’d say overall it’s pretty consistently great.
Watch. This. Show.
Especially the Season 6 episode “The French Mistake”, in which Sam and Dean are thrown into an alternate reality where their names are Jared Padalecki and Jensen Ackles, and they are actors on the TV show “Supernatural”. The whole show makes fun of the two, and Jared Padalecki even told the writers if they were making a parody of their real life they should poke as much fun at him as possible. And they do.
