Last night's ep... Sucked.
Not because of what ultimately happened. We all knew Abbadon was going to eventually resurface, and Crowley's play is absolutely ingenious.
What sucked is how stupid the writers made our primary heroes seem. It was embarrassingly poor writing.
Sam and Dean dig up arguably the most powerful demon they've ever met to cure instead of some chump demon? They didn't know at the time that Crowley was keeping his people away - this decision was made first.
Then they take her to a warehouse instead of their mega dungeon... And then leave her unattended. Stupid, stupid, stupid. Lazy writing, in a contrived way to get Abbadon back.
And then we've got Cas being manipulated, quite easily, into shutting the doors of Heaven... Even though he was running with the Angrl tablet for no reason other than to stop that.
I just don't get it.
