Key the Metal Idol Scans
The different genres here - psychological horror, action, idol girls, mecha, military, and the old androids dreaming of electric sheep question, are all twisted and intertwined in the strangest and most surprising ways. I would never have guessed that there would be an anime combining Shinto mysticism, conspiracy theories, idol singers, mecha warfare and cute robot girls and have it not be a Frankenstein's monster of regurgitated anime premises. It's certainly weird, and certainly interesting, but by combining all these, fans of the individual parts might be turned off by it. (I went in expecting moe robot Idol Densetsu Eriko at one point, and luckily I like enough different things that I wasn't bothered by finding it was NOT that.
When it was all said & done I though it was a good Anime. It started out o.k. but somewhere between disk 1 & 2 it just seemed bland. Like it was just going on and on... Once I approached the end of disc 2 going to 3 things picked up & grabbed my attention. I'm glad I stayed with it to the end. It was worth it.
