For me, as a Jewish Otaku, Anime about Anne Frank- real story about a Jewish girl that wrote a diary while hiding from the Nazis, means a lot. Still, I expected something better, the anime storyline didn't seem to follow her original diary, lots of parts were missing, the art wasn't even close to beautiful but somehow, an Anime movie about Anne Frank still made me cry. Story: The story doesn't seem to be great at all- big parts of te diary are missing- and somehow, I dont think these parts coul be replaced. No, these Anime is not good enough with these parts missing. Art: The artwas just awful, no other way to explain it.
Sound:
Wow. I was definitely surprised here. I didn't think an anime about Anne Frank could have such a beautiful soundtrack, a soundtrack that comes just in the right moment, and shows some hidden feelings that you cannot just explain.
Charcter:
I think here's the best thing in this anime. They managed showing the life of a teenage girl breaking out to pieces. They managed showing the way she felt, the way she thought. They made it all just, wonderful.

Anyway, I think Its a good anime to watch- but can't replace her original diary, though.
