I'm one of the few that's fed up with the BMOL and wants to get back to down and dirty hunting the Winchester Way. I'm also crossing fingers this isn't another set up for tedious secrets and lies and Sam keeping things from Dean and the soap opera angst we had to put up with a couple of seasons ago. Been there, done that, didn't want the tshirt.
The intro of Mary could have been SO compelling. Her reaction to her sons. Her reaction to their formative years with John. You know.. actually talking with each other - the way Amara intended (I think?). Mary was a gift after all. We could have been privy to S&D's surprise and pride as they discovered their inherited hunting instincts came also from mum not just revenge fueled John. Mom was a great hunter. Something to be proud of. Instead they've made her distant, uncaring, unlikable and making stupid choices.
And don't get me started on the Luci rerun or the Rosemary's Baby silliness.
I wish I could be as keen about the direction of season 12 as the rest of you. At least the Js are not phoning it in. When Dean said "Mary" instead of "Mom", it seriously stabbed me in the heart.
