New York Times:
Several of the characters in Dune are psychic, which puts them in the unique position of being able to understand what goes on in the movie.
The problem is that the imagery isn't rooted in any story impulse, and so its power dissipates quickly.
This movie is a real mess, an incomprehensible, ugly, unstructured, pointless excursion into the murkier realms of one of the most confusing screenplays of all time.
Most sci-fi movies offer escape, a holiday from homework, but Dune is as difficult as a final exam. You have to cram for it.
Lynch's third feature may have been a commercial disaster, but it gets under your skin and is marked by unforgettable images and an extraordinary soundtrack.
Dune is a huge, hollow, imaginative and cold sci-fi epic.
