From Star Wars: The Force Awakens, through Star Wars: The Last Jedi and going into Star Wars: The Rise Of Skywalker, Adam Driver has been on a very complex journey with Kylo Ren in recent years, and one positive development the actor has seen during that time is a stronger ability to communicate about the character.
While there was some original hesitance when he was first playing the part and starring in his first major blockbuster, that was something that evidently dissipated in the making of the ninth chapter in the Skywalker Saga.
