** STORY REVIEW - MINOR SPOILERS **
I enjoyed S1, but I felt the show kept sabotaging its comedy with its narrator. It's as though the show pandered to the least intelligent denominator by requiring everything to be explained. S2 still has the annoying narrator, but he doesn't talk as much, and he is kept out of the more serious moments, such as the two arcs. I wondered why the show had such a high MAL score. And then came episode 11, where Ishigami grows out of being a simp. I didn't expect that.
** END SPOILERS **
Kaguya-sama S2 falls short on the top tier of my comedy preference, which is "intelligent" slapstick like Aho Girl and Asobi Asobase. And the serious arcs don't compare to the best dramas. But what Kaguya-sama S2 did was blend both elements together into a show that satisfies almost everyone. It means that the show remains entertaining for all, though it lacked some of the thought-provoking moments of more ambitious shows.
Though I had a negative bias going into this show, no thanks to the narrator, I'm happy that this one ended up being a nice improvement over S1 with its skit creativity. The serious arcs were a nice cherry on top.
