Yeah; I think one of my big problems with SPN over the last couple of seasons is that I'm just not really finding the demon/angel mytharc particularly interesting. So the episodes that I've enjoyed most have been the ones that didn't relate to it in a major way. I'm also starting to feel like they really don't have anywhere else they can go with Sam and Dean that they haven't gone, except to the very dark place where it's starting to look like they're headed. So having them interacting in a very different way in this episode was pretty awesome for me; it recaptured some of the freshness of the first season.
