Okay here's some.
-constantly flipping his hair back or swiping it back with his hand directly after taking offense, when he should be selling he's hurt. if it bothers him so much after every movement he does wouldn't he just tie it back. rookie mistake psychology wise. (this will ruin his matches for alot of u as he does it way more than any wrestler with long hair, so I'm sorry for the "once u see it u cant unsee it")
-never jaw jacks the crowd during the match, he will do mannerisms to play to the crowd, but never talk shyt, so they end up being ambiguous af like it could be heel shyt or playing a "cool laid back face".
-he does nothing throughout his match to acknowledge he's even in bullet club, he does one "2 sweet" at the end. the big angle that was supposed to elevate him to the level of being able to beat Okada, and Gedo turning. It all means nothing and he might as well not even be in BC.
-the biggest heat spot in the match was nothing Jay White did, but when Gedo was on the apron. (psychology makes sense for ex best friends or whatever, but if Jay as good as you proclaim he should be getting all the biggest heat spots in this match)
-this dude is cutting a promo like he's lost the match and trying to make up excuses why. it's not confident and elevated, it's just whiny.
His in-ring fundamentals are very solid, but he's missing the little things to compliment them, and yes, that is a charisma problem. So everyone in this thread saying he's void of charisma is absolutely right imo.
