I was young when dune was released and a big fan of herbert books. there was also star wars that ive seen at the same time. Dune is still today to me one of the great SF movies and I count a very few I really love (cloud atlas is another more recent one, speed racer too).
All his weirder movies were great experiences but my favorite ever Lynch movie is the Straight Story. such a perfect beautiful movie. I loved badalamenti music as well: https://www.youtube.com/watch?v=aCzAetSFRC8&ab_channel=amast...
I always thought writing and directing a movie of pure kindness and making it interesting as a piece of great art was the real mark of genius.
