Okay, I Watched Dune (1984) - So Many Questions!

Alright, confession time: I finally tackled Dune (the OG one). And wow, it's... something. Before you come at me with spice knives, I know it's sci-fi, not rom-com, but a girl's gotta broaden her horizons, right? Plus, Kyle MacLachlan wasn't exactly hard to look at, even with that interesting haircut. The plot, though... let's just say I needed a wiki page open the entire time. Spice that makes you live longer, lets you travel through space...and gives you bright blue eyes? Sign me up (for the eyes, mostly). Honestly, the whole thing felt like a really elaborate fever dream. Like, Sting in a metal diaper? What was that EVEN about? And the sandworms! Terrifying, yes, but also, kinda phallic? I'm just saying what everyone else is probably thinking but too afraid to admit. I feel like the director (whoever that poor soul was) was trying to cram the entirety of the book into two hours, and the result was...chaotic, to say the least. I kept getting lost in the family webs and all the backstabbing. Don't get me wrong, it's not a bad movie, just intensely weird. The sets were pretty cool, in a very 80s way. And I appreciate the attempt at world-building, even if my brain cells were screaming for help. I think I need to watch the newer one now, just to cleanse my palate. Maybe it's a bit easier to understand, and perhaps less heavy on the metal space-diaper-wearing rockers. So, Dune experts, help me out! What's the part that REALLY sells you on this movie?? Was it the special effects? The story? Paul's glow-up? Lay it on me. And please, ELI5 the Bene Gesserit thing... I'm still confused.
