This teaser was ok, I guess... Being a teaser, it doesn't say much about the story, but still it does introduce some of the themes and characters (though, I wonder why that pilot keeps screaming. Dude. :D )
What I really dislike, though, was the color timing: just like in the other teaser, it has cyan and magenta completely boosted, yet high contrast, which means that shots that are monochrome-like (especially the chrome troopers' ones) feel very strange and almost make me puke.
Thankfully, yesterday they released those on-set photos. I don't know how much they can be of use but, using them as reference, I tried (I'm no pro lol) to regrade both the teasers to a more natural look: https://www.youtube.com/watch?v=Gmjqs8jtn0E
Not perfect, but doesn't it seem better? I really don't understand why they keep boosting colors like that.
