I cant rate the story when I've watched only 1 episode. But it was pretty interesting and enchanting. Which is pretty laudable. Very little anime make me interested in them from the very first episode. Though this one caught my attention completely.
And if I praised anime only by it's design and music.. well Guilty Crown would be my top favorite anime ever. I don't like plotless stuff, but it's really enjoyable to watch interesting, I repeat, interesting and meaningful anime with really good accompanying details like animation and music.
So now that I've watched some more episodes...
I like the way Hotarou thinks, pretty original. And I guess he's also smart, well deductive.

I want to see how his character will develop.
About Chitanda I like how she's persistent and so clueless. But she's also cute and pure <3
Still a lot to watch. But I can feel it's a great anime.
