It’s one shot which is really an issue, the one where he walks to Ren. The close-ups are fine (I say “bad” for a SW standard !).
it is the walk or gait you are talking about, right? it stuck out to me too, but it very well could be because of his disfigurement. basically, i am not so quick to call it bad or a mistake. but it doesn’t seem natural, that is for sure.
