I started watching Idol Jihen (Idol Incidents) because Ueda Reina is in it. Unfortunately, she's not in it much, although the OP suggests there will be more to her character later. The show itself is all right, but just barely. It frankly plays out like a rejected Aikatsu! arc, which is fine for a few episodes, but maybe not enough for a whole season. I was also expecting the entire Diet to consist of idols, but instead the idol parliamentarians are just various members of fractured idol-based opposition parties trying to challenge The Establishment comprised of old, unpleasant, corrupt politicians and uncaring corporate assholes.
Idol Jihen has its moments, but through seven episodes there's only been one episode I fully liked (the one with the gosurori ghostbuster), but that was mostly due to execution. I am a bit tired of the constant struggles against Old People. The show falls flat when it tries to present these battles in a semi-serious fashion involving such weapons as Children's Feelings. The show is much better off when Old People instead get swayed by idols doing idol things and everyone realizes how much better off the world can be after their idol epiphanies. Well, at least the OP and ED are catchy.
