Is this an exciting movie to see on a cinema screen? Yes. Is the movie and the actors' performances overhyped? Also yes. Dune Part 2 is exactly what you need from the second half of a story but it feels less...grand.
The universe building was in the first movie and besides a glance at Kaitian, home of the Emperor, and a brief visit to the monochrome seat of Harkonnen power, Gedi Prime, this movie focuses on life in the desert.
A luscious-looking adaptation of Clavell's 1975 novel FX's Shōgun is a worthwhile watch. You can tell there's money on the screen when the doomed ship Erasmus emerges from the fog. It looks like an oil on canvas painting. While the Samurai tropes are long exhausted, 17th century Japan at this scale may be an alien world to a Western audience. It feels substantial when you see it roll out in front of you and there is detail everywhere you turn your eyes.
