I might be in the minority but I liked the Dune movie. It introduced the universe, how it worked, had a solid cast. The movie is clearly one from the 80s with it's dedication to atmosphere.
From one other review:
"The second scene depicts the mysterious “Guild Navigator,” a brainiac character Lynch devises as a literal giant talking brain floating in a tank of brine. His mouth is triangular-shaped. There’s really no clean way of saying this, so here goes: It looks like a vagina. And it secretes gas. Lynch likes to shoot this in graphic close-up, and they’re explicit enough that if you see the film cut on TV, the editors completely omit these shots."

I respect your appreciation for the movie, but to most people it's objectively bad.
From Wikipedia:
"In retrospect, Lynch disowned the film and acknowledged he should never have directed Dune:
I started selling out on Dune. Looking back, it's no one's fault but my own. I probably shouldn't have done that picture, but I saw tons and tons of possibilities for things I loved, and this was the structure to do them in. There was so much room to create a world. But I got strong indications from Raffaella and Dino De Laurentiis of what kind of film they expected, and I knew I didn't have final cut."

That last scene with Neil Patrick Harris' character also destroyed that movie for me.
I liked the aesthetic of the movie (everything was 'old' and worn and staid). I liked the mini-series because it stayed closer to the original story, but (because of budget?) things looked too shiny: things seemed too 'fresh' for a societal structure that had been static for generations and generations.
That was kind of point of the Golden Path: you wanted the Imperium to seem 'static' because of inertia, and humanity needed something to shake them up from stagnation.
It's one of my favourite movies, however it deviates quite a bit from the books. Still good :)
I can see why other might not like it though.
