I didn't care for this episode, this show has fallen so far from what it once was and didn't Charlie work on that panel before? I don't buy that this whole time the bunker has been in stand-by mode.
I think the writers are super fans of Scooby doo and think they are writing for the cartoon audience. Dean wearing Scooby doo boxers and a nightgown, I don't think so.
The nest of vampires was 2 and Sam and Dean took care of them in like 3 seconds counting knocking the door down. I liked the wink to Ghostbusters but not the montage of breaking down the door, it's like an after thought the writers threw in, oh yeah, they're hunters lets have them hunt and for giggles lets through in Thor's hammer, WTF.
In my opinion, Jared doesn't even seem to be acting anymore.
I'm happy watching seasons 1-5 I'll stick with those.
