I don't know what to think yet. Am I going to see it in the theater? Yes of course, but I am going in with a bit of a doubt. Nothing actually happened this whole trilogy, it has felt disjointed from the other six movies and the overarching story is not really interesting. Recently I rewatched Episode 8 (through Disney+, which we're able to already have here as a test since last month, works quite well and already has a large collection, if you want to know), after not having seen it since I saw it in the theater, and I have to say it's story doesn't make sense. I feel you can just as well skip it. I still say Rogue One has been the only Disney film that actually felt like it belonged in the saga as a whole.
Hopefully, Lando and Palpatine make this movie worth it, like how Han made The Force Awakens better. This trailer doesn't really make me much more excited though, there's not much mystery;
and the trailer apparently spoils
Anyway, we'll see in about two months time.
