5 sci-fi movies deeper, denser, and weirder than Dune

The first Dune book by Frank Herbert came out in 1965 and changed sci-fi forever, but it was only recently that the book series finally got a decent movie adaptation thanks to director Denis Villeneuve. The first two Dune movies were both really good and really popular. With a third movie on the way, fans are no doubt jonesing for something to help tide them over. If you want a sci-fi movie as dense, deep, and delightful as Dune to watch while you wait, you have lots of options.
