Highly dislike Crusher and Picard never being resolved. Especially when the ending we did have heavily implied that the future Q showed Picard made him backpedal and decide he should never hook up w/ her if it would just end up in divorce. In my head canon, Q fictionalized that to keep Picard single b/c he wanted Picard for himself. It's sleezy! Picard and Bev deserve happiness and their chemistry on the show is the probably the best in maybe all of Star Trek. I just want my space-mom and space-dad to be happy. 
(Tangent: I really enjoyed PIC, and it's a fascinating look at the character, but it'll never not be upsetting to me b/c I jus want my boi to be happy.)
Worf and Deanna hooking up was great for Worf, because it was the culmination of his series-long character development arc of him becoming more comfortable as a person living between cultures and participating in both. Instead of always feeling like an outsider, or like he's betraying his Klingonness by doing UFP-things. In the beginning of TNG, he has an almost forelorn description of how he belongs in neither society. And a lot of his character episodes are about him learning that he can still accommodate and participate in human culture without losing his identity as a Klingon. And that Klingon culture isn't this static thing set in stone but something that changes and evolves (like all cultures do) and that he can and should be a part of guiding that evolution.
The problem with Deanna and Worf is that it does nothing for Deanna. Like, I never got a feeling for what she saw in Worf or why that pairing was something that would be a good mesh with her personality/priorities/lifestyle. It just never made a lot of sense because the writers didn't even seem to think about exploring it. It felt like she had no agency in this scenario and was just a tool for exploring Worf's character development, when a good coupling should be a story about how both parties complement each other. At the very least, I got a better sense of why Jadzia liked Worf and what she got out of that relationship.

Hammer of the gooooodsssssss
to me, Descent was probably the worst two-parter in the franchise, and most of the other two-parters you didn't have to wait all summer to see the next episode, at most you had to wait a week to a few minutes. So TL;DR it was the one that delivered the most on the hype. It also bridges Seasons 5 and 6 which are the best seasons. It just represents peak TNG to me.
