It's more about Genndy not being able to pace his show for shit and wanting Ashi to be his childhood waifu. Episode 7 should have been about Jack getting his sword back and Ashi fighting her mother so that she could protect him. Instead, Jack getting his sword was incredibly rushed and Ash's complete interaction with her mom was pulled out of nowhere and lasted only 2 minutes. Episode 8 should have been about the two actually getting some time to bond, but instead most of it was B-tier romcom dialogue and "OwO notices ur sword" innuendo.
After setting up Season 5 as something that takes advantage of its TV-MA rating and audience, it started taking a dive after Episode 6 was a mess of cringing Ashi scenes and rushed pacing to fit all the untrimmed content. It was understandable to an extent since it was meant to be a fun episode, but Genndy has turned that into a permanent and poorly done tonal shift instead. The quality of it is leagues worse than episodes like Jack and the Farting Dragon, and it lasted for a third of the season.
It's not the principle of the matter. Genndy just wrote it like shite after 5 stellar episodes.
