I had the princess pegged since ep 2.
I have mixed feelings about the show because of this. I like how it is a fantasy-based show that is also simultaneously a mystery. There's no murders which also makes it enjoyable. The characters are evident and each have their respective flaws and whatnot. But the problem with this show is that it is very predictable. If I can peg the primary antagonist literally two episodes (and this is not including my thinking that the princess was already weird in the first episode) into a show that is supposed to revolve around the mysterious identity of the villain then that's a problem. Of course that's a problem with most closed room scenarios in the first place as the fog literally creates a closed room scenario where we are forced to suspect only the people within the barrier, and the writing directed us to think this way as well. Limiting characters like this is classic to mysteries ala Agatha Christie-style, but the biggest issue is that how characters are portrayed often times can make it easy to figure out whodunnit. I guess for me, I expect mysteries to be handled well in how they reveal a plottwist (the Umineko manga does an incredible job with this, and as does the Zero Escape video game series). The poor use of red herrings and the fact that characters are easily eliminated suspect-wise via process of elimination hurts the show. Perhaps it's also just a limit to the medium, as with manga/books you can be much more methodical about information that is given to the reader, whereas with anime you have to factor in the tone of the voice acting as well as how much you want to reveal in scenes animation-wise. And you have that god-awful cliffhanger at the end....sigh...
