Black Panther shouldnt be anywhere near this list. Its an average to good film, massively overhyped and inflated. It is a better Marvel film but still not a good film and its cinematography is nothing special while the less said about the CG elements the better.
It is about the gear when youre talking about Alexa though. I've shot on Alexa and on C300 and FS7 and C100, 5D even back on old sony DVCAM when i first started, and yes you can shoot really nice stuff on all of them, but do you think this would have looked half as good shot on a 5D? You would have needed so much more light creating fill, the highlights in the window would have blown out, the fall off into the shadows would super harsh and the skin tone you've got wouldnt be as nice. It can be done but not with entirely natural light through a window and some haze. There is some good advice about doing what you can in post and building connections and such but the under $1000 low budget is a bit of a laugh.
