I haven't read the original novel in about twenty years so I can't speak on how accurate this is, but it is pretty close to the recent movie version, so there's that. Since it was adapted by Kevin J. Anderson and Brian Herbert I assume it's pretty faithful.

The artwork is really clean and I like the character designs, although I find the more science fiction elements a little disappointing (the Ornithopter for example) when compared to the concept art from Jodorowsky's Dune or the 2021 film.

This is part 1 of 3 but it works quite well as a stand-alone story, although obviously leaving things on a fairly major cliffhanger.
