I think it was a bit better than the 2nd series, but it needs a lot of work if they want to keep people interested, the story felt a little bland though, at least there was a hint of one, still, there wasn't a blinding amount of fanservice which is a plus, though i admit that i am only watching it to find out how come sylpide becomes human (or does she?
)
All in all it does have potential, besides there is a whole series left so it could turn out really good (though that is unlikely in my opinion)
