I never thought I would ever find Supernatural boring but this season is really mortally boring. There's no plot besides this Kevin Tran thing lingering in the back, Dean thinks he's a wonder with his heavy fake tan and throws faces and nasty jokes to everyone all the time, Sam is dealing with some stuff, again, but less convincingly this time, Castiel is not enough on screen but comes just to add a layer to that old humorless-angel and naive behavior, Crowley has no more trick in his sleeve ...
So they count on other character to put some kind of rhythm in it, such as Garth or Charlene (?) but that's not enough when titans like Bobby or Lucifer are no longer here to support the adventures of Sam and Dean.
Even in this episode, where we meet an important member of the Winchester family, which would be impossible in real life, I wasn't convinced. Now that every Winchester has been met, what's left to boost the story? The grandma? However, the character of their grandfather (father side)was pleasant. We apparently have to believe that everyone in this family was a model-type man, and there's the fact that a man living in the fifties, with a very correct language, understands perfectly Dean's mumbling and slang. Okay. But besides that, the story was nice to watch.
It also brings an important question : will there be a legacy to Sam and Dean? Winchesters and Campbells were married and had children but it seems impossible for these two. Will it be on their shoulders to eradicate every single nasty thing on earth?
I hope the show will bounce back because that's a real crime to waste such good material.
