Pretty accurate. Most of the first movie is basically the prologue to the main story.
The first movie is extremely loyal to the book; I have yet to see the second movie, but I would be surprised if it wasn’t much the same.
Funny thing: theres a surprising number of Dune references in The Grim Adventures of Billy and Mandy.
Also, military veterans generally don’t recommend signing up anymore. We’ve also had something like 40+ years of live combat and other reporting for the military, so people know what the fuck they would actually be signing up for.
