I love this article. This completely sums up my feelings on both the finale and season seven as a whole. I’m going to throw in my two cents now.
I thankfully haven’t found any yet, but I can predict the inevitable wank that the separation of Sam and Dean will cause in the fandom. I for one think it is an incredible opportunity for development for both of the brothers. Yes, I’m bouncing off the walls in excitement for Dean and Cas being trapped together somewhere, but that doesn’t mean I’ve forgotten about Sam. I can’t stand the argument that secondary characters aren’t important in Supernatural because “the show is about Sam and Dean.” Yes, Sam and Dean are the focal characters, but how can we expect them to grow if there is never anyone else to give them a new perspective? The Sam-and-Dean-alone show worked in the early seasons because they were still learning from each other. We don’t feel like we’re missing too much with the lack of recurring secondary characters in seasons one and two because they are growing, changing, and still relearning how to be brothers. Once you introduce characters like Castiel, Gabriel, Ruby, Jo, and Ellen, you can’t simply “return to the basics” and expect it to feel the same as the young hunting brothers we loved in season one.
I’m sorry if you hate Castiel and don’t want to see him interacting with Dean in any way. I personally think you are missing out on a brilliant, beautiful character but you are completely entitled to your opinion. However, the decision to leave Sam on Earth and bring Dean and Cas together to Purgatory was a really smart narrative decision. We’ve seen all of the ways that Sam and Dean react to bad situations together. We’ve seen seven seasons of it. It’s been a long time since we’ve seen Sam forced to be his own person outside of his brother and while it aches my heart, I’m really looking forward to watching how he deals with the separation. I’m hoping for the return of Jodi Mills, personally. Despite the shaky forgiveness in the last episode, Dean and Cas still have a lot of bad water under the bridge, and being stuck together will force them to reconcile and perhaps give them (mostly Dean) new perspective.
Those are my thoughts, anyway. The article is really wonderful though; I think anyone current on the show should read it.
