I need to catch up with a few of them, but the first episodes all held up nicely, I have a preference for Mahoutsukai no Yome, but that's because I waited literally 3 years for each OVA to be released before the TV show, waiting so that I can binge watch it, first 3 episodes where good, not as good as the ova, but good.
Classroom of the Elite was interesting, It's nice to see an MC that isn't boring, I feel as if he could be quite the character, if there's a season 2 then I'll definitely watch it.
