So I'm a Spider, So What? - Kumo Desu ga, Nani ka?

[Ryllharu]

The human side of the story is just the absolute most generic cliche fantasy isekai crap that I have seen in literally dozens of other shows. Only without a single fun or entertaining character.

Disagree. They're interesting together and the time split between them makes it much more interesting than either part solo.

Kumoko's perspective is very limited. She knows about the administrators (on the human side, only Oka, Shun, and Hugo do as far as we know), she knows that the world is going to end because her Taboo maxed out, but she's supremely ignorant of the world outside of the three layers of the Labyrinth.

The human side gives the audience perspective.

Kumoko is big picture endgame. Shun, allies, and demon side are big picture world-building.

Further, we know where the story is now, so it ramps up the anticipation for how Kumoko gets there, whether or not she's actually alive 15 years later, and where she will slot back into this future state when she does.
