Supernatural! Two brothers stuck fighting for humanity against all that life can throw at them, and unfortunately for Sam and Dean in Supernatual life throws hell of a lot! We have seen them fighting Vampires, Ghosts, Shapeshifters, Demons, Angels. The Winchesters even took on Lucifer himself and won. This show is brilliant and I keep coming back wanting more.
The story follows a newly formed team of S.H.I.E.L.D agents under the command of Agent Coulson, known from the Marvel Movies. Season one starts of in a "monster of the week" type fashion with the story arc quite slowly but introducing the characters and allowing you to come to love them. Around mid season the format changes and the story reacts to the events of Captain America: The Winter Soldier and you get to see the knock on effect for S.H.I.E.L.D and the agents after this point the story really picks up and there is a lot more action. This show has it all Action, Romance, SciFi defiantly worth a watch!
