Yeah, season one and two were awesome! Season three had it's great moments and season 4 and 5 were mindblowingly good, so it makes you begin to ask: when are the writers going to run out of steam? Or when are the main actors going to get sick of their roles, which usually happens in something as long running as this. However this was not the case. Once again, Supernatural tops itself with great acting, clever writing and excellent direction. First of all, Jared, Jensen, Misha and Jim Beaver are and will always be awesome actors. I wish i had a quarter of the talent that these guys have. Crowley and Balthazar are also characters where the actors are splendid. Rufus is brilliant! To see Ellen again is a pleasant and wonderful surprise. Not to mention, the guest stars and ensemble cast are also flawless.
And as for the writing, there are so many great episodes in this season that it leaves me speechless. For example there's Two and a half men, the third man, frontierland, weekend at bobby's, like a virgin, death at samarrah, you can't handle the truth, clap your hands if you believe, unforgiven, the man who would be king, mommy dearest, my heart will go on, the french mistake. the man who knew too much, and caged heat, are all great episodes. And I'm pretty sure there are some other good ones that I'm forgetting in there too.
And the funny thing is I am not a horror fan at all. I never like to watch scary movies and I am a hopeless Jane Austen/Bronte fan where I love to re-watch old classics. Don't get me wrong, I love action/super hero movies also, and artsy stuff like Coraline, Stardust, and Nightmare Before Christmas. But still, the fact that I would put down Jane Austen or the Bronte movies in a heartbeat and put in Supernatural instead shows how great this show is. It took someone who didn't like that genre, and makes them like that genre.
