I don't know, I understand where you're coming from but I really liked those aspects. I liked the premise of losing 3 years and trying to regain them back. I liked the struggle Haruka and Mitsuki was having but hating Takayuki. It was just a fun animu to watch and rage about. Anticipating and trying to guess what would happen at the end. Not to mention I marathon'd the whole thing so there was almost no wait between the episodes.
The animu wasn't supposed to be DEEP, but it was interesting trying to draw out different meanings at the end such as the character's motives, where they were coming from, through trying to interpret where they were coming from.
Like Mitsuki's case and how even the fans hated her for the "backstabbing" but in the end, the characters were just human.
Btw, I'm curious, did you watch the animus as they were airing or did you watch everyone in one sitting?
