I think the absence of Dr. Psycho made a bit of a difference. When he came back for an episode it felt like it did in earlier seasons. I know some fans specifically hated him but I found him funny.
I also feel like there's pressure for the writers to get the Harl-Ivy relationship right. I've noticed on shows I've watched with lesbian characters there seems to be a higher pressure from both a narrative aspect but even more from a representation aspect, like there are lesbians who watch this simply for the ship and they very outspoken on social media.
Also, I watched that trailer and this is a small irrelevant gag but seeing that dog mount the cat. After knowing someone who bred dogs and how that happens and them getting 'stuck' that shyt is horrifying.
