This is the sequel of Magical Girl Lyrical Nanoha, another anime I really liked. The series starts out pretty decent. A new enemy appears, who defeats Nanoha in a fight. The premisse of another one of those action series.
Well, those predictions get totally trashed into the ground by the next following episodes. The creators managed to create the most amazing person for the "antagonist" of the show, and the other bad guys have some of the most depth ever seen. Especially the middle episodes are just too sad to watch, and they only get better and better as the story unravels.
But yeah, with a show like this, there was no way for the ending to be not predictable, and yes, the last two episodes indeed seem to go right the way you suspected it. Still, the creators manage to make something decent out of it.
The characters, as I’ve already said, are extremely well developed. The main characters may look a bit like other main characters, but all the other characters totally make up for it (after all, Nanoha already got her screentime in the first season, so now it’s time for the other characters to shine, the creators made the right choice for that).
As for the graphics and sound department, this show certainly delivers. The art looks great, the character art is extremely cute and the CG looks amazing. If you however, compare it to the prequel, it’s very hard to see any improvements in it. You would expect that the creators would put a bit more time in the show to make the graphics even better. The music also is wondeful, fitting each and every scene. Well, almost every scene. The ED and the commercial tune really break all of the tension the series had been building up. That is a bit of a pity.
Why you should watch this: If you like cute character art, a heavy dose of morality and furthermore a great story, then you should watch this.
