4. Castiel & Crowley
Castiel, he is my favorite Supernatural character. The character of Castiel has undergone many transformations, as an angel, he had no emotions towards humans, he blindfoldedly followed all the orders given to him and had no room for disobedience. But his time on earth and interactions with the Winchesters have a humanizing effect on him. He starts displaying emotions and cares about humanity welfare. And well Crowley, he’s the demon that you simply can’t hate. His character often shifts from the main antagonist to the anti-hero in the series. He helps the Winchesters because he needs him.
5. Supernatural Stuff And AWESOME Soundtrack!
Leviathans? Vampires? Witches? Werewolves? Demons? Angels? Satan? God? Satan? And the list can go on and on and on–But you get the picture, you just name it, Supernatural has everything you’d want. Great music like Iron Maiden, AC/DC, Metallica, Kansas is featured in the show. This makes the show even more AWESOME!
