Hmm. Can't really comment on that.
I touched on this before, but I still don't quite see the point to the Celestia arc, since it's supposed to be building up Roy's family relations as something of vital importance when we already knew that Roy had mixed feelings about his Dad for reasons that aren't hard to grasp and could have been handled in flashback at any time if more detail was warranted. Either way, the Blood Oath doesn't care.
I didn't mind the New Year's arc in itself... aside from a nagging sense that Miko fans were being deliberately pissed on. I could be biased, though.
