How was Aku no Hana's rotoscoping received by other animators? In the anime version of Aku no Hana, the animators chose to use a technique called Rotoscoping:


  Rotoscoping is an animation technique in which animators trace over footage, frame by frame, for use in live-action and animated films. Originally, recorded live-action film images were projected onto a frosted glass panel and re-drawn by an animator. This projection equipment is called a rotoscope, although this device was eventually replaced by computers.


This resulted in the animation looking more realistic and quite different from typical anime, as pictured below.



Online, I've seen both love and hate for the style, but I'm wondering: Have any Japanese animators commented on it? According to TVTropes, it has a bad reputation in the West with animators such as Richard Williams and Milt Kahl, but it makes no mention of Japanese animators.
There's not much information out there, perhaps because it is bad practise to criticise fellow animators. But there is information from the people who were involved:

Firstly, The mangaka was satisfied with the way the anime was animated, and the studio itself was happy with the outcome, wanting realism without making it completely live action and wouldn't be opposed to doing it again with another series, mentioning that Mushishi would be a good candidate for the style.

Vertical Inc., who publish the manga in English, have also stated their support for the stylistic adaption - Vertical Inc. Tumblr

The industry as a whole isn't opposed to rotoscoping in the industry, Kuuchu Baranko also implemented it for one character's appearance and there was little outroar on the internet



Kids on the Slope also used the technique for animating the characters playing instruments, most notably the drums;



It also wasn't the target of much negative feedback either.

Personally, I think that if a large unconvential stylistic choice was made for an entire anime, there will always be negative feedback, and that makes a lot more noise than positive ones.
