It was pretty great. I was reminded a great deal of Perfect Blue, which Oshi no Ko can never be, but it was still great for what it was. Glad they didn't take the reincarnation thing in a creepy direction. Maybe it's just me but I thought Ai was a bit too pure, even behind the scenes. It definitely begins to scratch the surface of the messed up idol industry, which has only gotten worse since the release of Perfect Blue.
