Since Neon Genesis Evangelion has impacted upon the anime landscape in 1995, there has been a continuing procession of overly dramatic and angsty teenagers in anime series, masquerading as “deep” character development. Which it really isn’t, and works detrimental to the rest of the anime.
Which is kind of sad, since Noein uses some interesting concepts rarely seen in anime, like Everett’s many worlds theory and other quantum reality ideas, and has a unique style of animation which I liked. But the annoying teenagers really made watching this feel like walking over broken glass. If the drama queen aspect doesn’t bother you, then this might probably be a much better experience, but for me it was the breaking point.
