Anime Anime News Network (ANN) editor Carl Kimlinger gave the series high praise when it was streaming, giving credit to both director
Hiroshi Nagahama and composer
Hideyuki Fukasawa for doing Oshimi's work justice with direction that is part psychological thriller and darkly romantic with the inclusion of rotoscoping and a score that is atonally sinister, saying that, "[I]t is a series that can be attacked from any direction and not crack. It is, in its delightfully unpleasant way, a masterpiece." Fellow ANN editor Nick Creamer also liked the series, praising the story for conveying themes of human identity and codependence with amoral people and the direction for its slow and methodical pace, concluding that "
The Flowers of Evil is one of the best shows of recent years, an absurdly confident mood piece with a uniquely effective aesthetic and a true understanding of and sympathy for the emotional trials of youth. It should be watched by anyone interested in the potential of animation for conveying human truth." Richard Eisenbeis of
Kotaku, on the other hand, heavily panned the series for having an unlikable main cast, lack of any stakes or tension, and horrendous technical aspects in terms of animation and no musical score in places, concluding that, "It's just an utter train wreck of a series. I recommend it to no one." Tim Jones, writing for
THEM Anime Reviews, was also put off by the rotoscoping style, saying that from a distance it looks "comical and oft-putting (sic)." But Jones gave praise to the cinematography, the main trio's development and Nagahama's direction on a typical high school setting. Jacqueline Ristola argues that Nagahama uses rotoscope animation "to visually represent the series’ themes: the divide between the private and the public, the use of masks in society, the sense of alienation, and the concealment of one’s ‘true self.’" Chris Beveridge of The Fandom Post wrote: "This has more life to it, more meaning to it, than pretty much the majority of shows out there because of the acting, the story and the presentation. This is definitely the kind of work that can start some seriously great if difficult conversations and is worth exploring, even if only for yourself." Ink of
Otaku USA chose the series as his pick for the Top Anime of 2013, praising the performances, sound design, pacing and rotoscoping technique for delivering "an oppressive atmosphere of anxiety" in a high school setting, concluding that, "If you like slow, moody pieces,
Flowers of Evil is a must!" ==References==
