I got tickets for December 15 (the night before it comes out).
I'm going to go the night it actually comes out too, assuming I can get tickets. I don't think there should be an issue, because there's not as much hype with this film as there was with
The Force Awakens.
I still think it's going to be really good, though.
Star Wars has such a large fan base that it's bound to do well regardless. There isn't hype like there was for the last one, though, which makes sense.
