Well, just watched the first episode. I'm currently reading the manga right now so I already digged the plot and the characters. I enjoyed the ost a lot. It just seemed to fit the scenes so well, and I can't wait to hear more of it. The animation was nice, and I'm glad that they changed it a bit from it's appearance in the manga. As for the voices? Lucy's is pretty fitting, I suppose, and I enjoy Natsu's a lot, (since the voice of Kamina is doing it, lol). Overall, very nice, and I shall continue watching.
(And the ed was the cutest thing ever!)
