I like those photos. Funny how having a set actually grey makes it look way more Star Wars than the blue tint they've added in the trailers. The whole teal and orange thing is a big fear of mine - modern colour grading sucks. It's a lost art, colourists need a hard slap.
On a related note I'm all for them shooting on film, but if every step of the post production process is digital it's going to look digital. The only advantage I can see is that film is virtually future proof in regards to 4k, 8k and whatever inevitably follows.
I haven't read the story stuff, got to stay clear of spoilers from now on.
