It was the moment we were all waiting for.
I was one of those weird people who thought that the rotoscoping in Flowers of Evil was a cool visual choice. I also thought that the long, brooding silences while the characters walked over a static background were great at establishing dread and the sense of inner turmoil that we all experience as preteens. Remember when everything was so damn important yet in retrospect our problems could've been easily resolved and were also most likely pretty stupid? This is a show about that.
...And then the last episode happened, informing me that the series was really about unhinged teens. Oh well.
In any case, there is one scene from this show that does not deserve to be ignored: the destruction of the classroom. It's what the slow build pays off in a big way, and it's amazing to watch. Kasuga finally lets out his inner demons, throwing chalk and covering the room with ink while Sawa spun in the center of it all. Not to mention the creepy ending theme playing over it...
I don't care that some people think that this show wasn't "anime" enough. A compelling scene is a compelling scene.
