IT WAS SO BAD! It was perhaps the most underwhelming and boring Supernatural season finale; it looked bad with the terrible wire-fight choreography, and I'm not sure if you saw it but there was also a terribly cheesy freeze-frame zooming into Dean's face at the very end to finish the episode off. And as you said, season 5 was rendered totally pointless with how "world-ending" the fight between Michael and Lucifer was. And it was entirely predictable that Michael would obviously not stick to the deal with Dean and he'd be the new big-bad for next season. Ugh, it was all terrible.

 

Hmmm nothing this season can come close to that season 4 hacking one I showed you last time. There weren't really any scenes that stood out. It was more just storyline and dialogue choices that didn't work.
