The ending to Pandora Hearts.

I mean, sure, let's face it, not a lot of Anime will be able to have all of the manga, I understand this. However... the ending was not only rushed with its whole, "OZ! Don't look behind you at that giant picture of a plot point!", but they decide to end it with a spoiler for later in the Manga, and not even do anything with it. It was like, "I know you're the main antagonist daddy, but I am my own person, and I will live life... COMFORTABLY!" Then it just sort of... ended without any true resolution except for that little thing about his dad, which going for the canon they set out, wasn't a big issue on Oz's part.

They didn't even bother making new designs at all, with the creatures being rehashed from the previous episodes >_<
