I've been on a binge, but I'm currently finishing up Blue Exorcist: Kyoto Saga. I really love how they originally ended Blue Exorcist and still find it more fitting than Kyoto Saga, but Kyoto Saga was a nice alternate ending. Never read the manga, but I hear the original was way different and Kyoto Saga is the ending "it should have had". It's a great season, but after having watched the original ending I'm finding the development just lacking in so many ways. The original just had more depth! :( I do really love seeing Suguro's background, though, and learning this side of the series. If the two had merged (if the original were given more time....) I think it would have been a really kickass ending!
