I admit I'm a bit optimistic in assuming that anyone where has watched it.
I enjoyed the first part (admittedly as a captive audience on a plane), but I did notice how they made the Fremen, who speak Arabic, half-black and half-Arab. Apparently, the Fremen are yuge racists who don't interbreed with the blacks among them, or if they had, all of them would be a mix of the two. But there was a clear dividing line between them, as if there's been segregation for centuries.
My beef is that Paul is also supposed to have been training his whole life in Bene Gesserit body and mind control, and, as the heir of a noble house, he's also been training as a fighter. He's young, but not wussy.
I also am just not a Chalamet fan, so there's that.
My stuff is really just nitpicks. I don't have any major complaints about Dune, it just doesn't didn't do anything for me.
Weird and at times BAD as it is, I prefer the 1984 Dune. I liked the miniseries too, but I haven't seen that in a long time.
