Attention to detail when they could have been sloppy.
Little things like the mk25, uniform sharpness.
Chris Pratt is a little stuff when wearing actually uniforms, though I think he’s trying to respect the uniform and wear them sharply, but most Navy guys are pretty loose. (not Marines)
As for the story line, great job throwing the viewer in and making us feel like we got the confusion.
Cinematography and sets are big picture movie quality, as opposed to lower budget network shows.
