Dune the movie? Or Dune the mini series from SCI FI channel? Both SCI FI Mini-series of Dune and Children of Dune blow that 1984 crap right out of the water!
The original David Lynch Dune.
It’s not an easy movie and unless you have an understanding of where it was going before you see it, you’re quite likely to end up confused. Since I had read the book before going to the theater, it made more sense to me.
The SciFi variants were extremely well done and I enjoyed them quite a bit.
