Well, another awesome adaptation!
Story: 8
The fidelity with the original story is amazing.... up to a point.
They spent too much time in little irrelevant details in the beginning, and in the end had to stick 5 chapters in 23 min. Not good at all, they simply cut A LOT of stuff, and shorten a lot of emotional scenes.
The ending was much less melancholic and deep than the original because of this cut.
It would be 10 otherwise.
Art: 8
There are some akward lines that they drew arround people's eyes. It looked fine in the P/B manga, but ir really weird in colour.
Sound: 10
The soundtrack is amazing, and not only the awesome OP (Lonely in Gorgeous - Tommy February6) and ED (Do ya wanna - Franz Ferdinand [YES!!]).
The background songs from the atellier are natural and pleasurable. It's an OST worth downloading because of the CD that would be kinda 'show' of Arashi's band, being pretty good J-Rock songs.
Charachter: 8
Again, the time spent in useless somehow made the carachter much less deep than in the manga. And Arashi's personality is quite different also.
Enjoyement: 10
I guess I explained that already.
To sum it all up, VERY worth it.
Despite being really recommended to read the end of the manga later for better understanding.
