Trying to work out the worst story arcs of this show

The appearance of Gen Zzzzs in the finale reminded me of that horrible podcast XYZ. Then Che's comedy concerts. But what was the worst storyline for you?

For me, strong contenders are how they turned Aidan into a jerk. Should've just left him as the one that got away.

Also, the cringe morphing of Miranda via that Nya person and the wokery at the start as they tried to redress the (im)balance of SATC all at once.
