So I'm on my umpteenth viewing. I gotta say, my biggest gripe - and it's a very minor one at that - is that there is no backstory on the Black Order. I get it, you can only cram so much into one film, and hindsight is 20/20. But, in hindsight (can't stress that enough, because this isn't really a dig at the film), I would've loved to see just a taste of them in a couple past films like they did Thanos. I know they probably didn't have the designs worked out and how they were going to be used in the film, though, if at all. Ebony Maw is such a cool villain to me and I'm sad every time I watch that he gets taken out so early instead of Cull Obsidian and co.
Which leads me to a couple questions - forgive me if I've asked before. Why was Cull Obsidian renamed to Black Dwarf? I don't believe any of the Order are mentioned by name in the film anyway, except when Thanos asks about "The Maw." An odd choice, especially for a character whose name is never mentioned and who has absolutely zero backstory or spoken lines.
