The “emo” thing bugs me. Luke was whiny as hell, and people seem to love it.
Yeah but Luke wasn’t a villain.
And also, Kylo’s arc wasn’t built as the film moved along. I could maybe see a place for complex villain wannabe (although it’s tiring by now), but by the end of the film he should be losing his mind and tipping over more and more to the dark side. Technically he kills Han, but it doesn’t really work one, that scene wasn’t all that emotional, and two, because of his gradual unmasking, and eventual emasculation by Rey. By the end of the film he’s just a putrid pretender, and can’t be considered a real threat to our heroes.
