Maybe its just the idea that he's conflicted is what bugs me about him. I dont need that from my villains. I typically like them to be pretty one dimensional, like Vader was. Just a bad guy on a mission who doesnt have all of this other information going on, he's just mysterious. As soon as they start making them out to be more than that, it kinda starts taking away from what I look for in villains, to just be an obstacle for the protagonists. Same reason why I love the Joker. Hes just a maniac, and thats all he is. I dont want to know all this other stuff about him.
Seeing Kylo crying, losing his cool, having daddy issues, looking so clean shaven when he takes his mask off... dunno, not my thing I guess. I actually like Darth Maul a lot more than Kylo, and he only has like 1 line in 1 movie! But he looked super cool, was basically a ninja, and only had one goal, to kill people. The character depth I like getting from the good guys, not the bad guys. Like with Luke, he was somewhat tempted by the dark side, so there was conflict in him, but not in Vader. Vader was just some guy with a mission.
I actually would have been ok with a lot of this stuff with Kylo had it been left for the novels. Almost like Force Awakens starts off where it ends right now... Kylo is further along, and we get hints about this stuff, but its not an entire movie about his conflict like 7 is, and it really made the character come off like he was very weak. When Rey defies him and even insults him, I really needed him to buckle down and cut her hand off or something, to show his resolve, to show he is the BOSS, but then he just ran back to Snoke with his tail between his legs looking like an upset puppy. Totally turned me off to him and wanted him to grow a pair. Really the only thing he did in this movie was kill a 90 year old defenseless man. Outside of that he just walked around, got insulted, then got beat up by a 19 year old girl.
He is really cool all the way up until he takes his mask off and the character drops off a cliff after that for me. He seems to start the movie off pretty strong, then actually gets weaker as the movie goes along. I have high hopes for him in 8 but in this one it wasnt working for me in the 2nd half of the movie. Still almost want the figure though just because he does look sharp in pix. Very photogenic.
