I watched the CrystalNova subbed episode 1, and it left me with very mixed feelings. It was clearly one of the mystery episodes. We had a couple of those in the first season as well. Now, it could be just my opinion, but this series seems to be divided in two: Totally realistic episodes and then more unusual episodes with heavy mystery feeling. I liked the realistic ones bettew, as they tended to concentrate solely on the characters, whereas the mysteries didn't really hit my tastes that well.
And then there were some graphical peculirities as well. I'm not at all one of those people who have very keen eyes for graphical details in anime, and who spot immediately if the budget has been slightly smaller or other things like that. But now with vastly different camera work, long still shots and other changes it didn't quite feel the same as the eps in the first season.
Well, I hope the second ep will turn things back to normal. I will personally stick to CrystalNova just for the sake of consistency, so I'll not be seeing the new eps all that quickly, I suppose.
