Just a brief entry for this one because my favorite Big Bad was Lucifer and I talked about him on angel day. He was scary during S5 as a corporeal bad guy and scary for a whole boatload of different reasons when he came back as a hallucination in Sam's head. There have been a couple of other big bads I've liked. Ruby had me guessing right up to the end. Azazel was a well-crafted villain with a great story arc. Although he was only in on the action for a few episodes in S4, Alastair was really important to Dean's story that season. Dick Roman was a great send up of motivational speakers and American corporate culture. So smarmy and predatorial. I liked the commentary on our food supply too. I wasn't crazy about Crowley or Cas as the big bad. I'm really looking forward to Abaddon's run. She's been awesome so far. I can't separate Metatron from his revenging nerd days and find him more annoying than scary. Maybe Abaddon will squash him like a bug.
