I actually really liked the exchange with Finn and Poe where it's heavily implied that Leia entrusted Finn with the knowledge of Rey's heritage, and then Finn says "that's for damn sure" in response to Poe saying "Well I'm not Leia." That one little exchange managed to deepen Finn's affection for Rey, where he knows the truth but it actually makes him feel more protective of her. It also serves Poe's arc in the film of not feeling like he'll be able to carry the baton from Leia and lead the Resistance. And then of course in the end, he and Finn end up sharing the burden together as co-generals.
It's a little touch, but somehow that one little moment felt like it added more depth and meaning to the characters' relationships than much of the previous two films did for me. I still think TROS had the shell of a good story. I think the character arcs and themes work on paper.
I came across this article recently that analyzes how ROTS and TROS have some parallels in terms of both films dealing with a breakdown of trust between the main characters, but obviously ROTS being an example of where things go wrong and TROS being an example of things going right.

I think it raises some valid points and it's why I consider the character arcs in TROS to be much stronger (at least on paper), than the ones in TFA. People give Terrio a hard time, but honestly I still think he's a good writer. He just keeps getting himself involved in giant projects where his ideas get chopped down and compromised due to the Hollywood machine, for lack of a better word. I would honestly love to see his full ideas for TROS, as he's even mentioned that he wished they could've done two films. If anything, TROS feels like an overstuffed film with too many ideas, while TFA feels like an empty film with not enough ideas. Both can be problematic, but I'll always appreciate a case of the former over the latter.
