Mark Hamill made it painfully obvious he was not a fan of the Sequel Trilogy. He didn’t like what JJ Abrams did with Luke Skywalker in The Force Awakens, and especially hated Rian Johnson’s direction of Luke in The Last Jedi. Then during the movie’s marketing campaign, he was contractually obligated to keep quiet of his true feelings towards the movie. However, now with that all over and Disney/Lucasfilm now focusing all their efforts into SOLO, Mark Hamill has no more reason to keep his true feelings, and future with the series a secret.
