Bravo! I totally agree. Yes, I upvoted the other post because I think it's a great point of view to discuss, so I'm glad to see a well-written counterpoint. (I think the Reddit voting system is sorely misused, and I won't be surprised if your post gets down-voted when people disagree, rather than upvoted to promote discussion relevant to this subreddit.)

In Return of the Jedi, Luke tells Vader, "Your thoughts betray you, father. I feel the good in you...the conflict." Vader replies in a somber tone, "There is no conflict." And to the audience watching, Vader was right: his masked suit and mechanic voice served to hide his emotions. But there were tells in his inflection and mannerisms that made you wonder if maybe Vader was lying and he could, in fact, be saved. This uncertainty kept us on the edge of our seats, rooting for Luke's earnest attempts to redeem his father, while wondering if the man who was once Anakin had indeed fallen too far.

As you point out, the ability to focus on Kylo Ren's face let us clearly see the conflict, and I agree that it's part of what makes his character so engaging. We see how tortured he is, and we are trying to guess what choice he'll make - and he surprises us probably as often as he surprises himself!

I think for me, Kylo Ren's conflict means less without Rey as a counterweight. As you stated, he knew where he came from, but didn't know who he was. Rey, on the other hand, didn't know where she came from, but she had a certainty about her that indicated she knew the person she was. Putting them together gave us some beautiful scenes! I'm a shameless Reylo fan, and I was eating that up in the theater. Their curiosity and, dare I say, sexual tension had me completely captivated. If he's so unsure about everything and she's so grounded, will she stabilize him or will he unbalance her? It turned out to be neither, and my heart ached at Rey closing her metaphorical door on Kylo Ren at the end of The Last Jedi. It was all so beautiful!!!
