I love the first Dune book, and I love the goofy 80's Dune movie, which was pretty close to the book in terms of getting a lot of the internal dialog in place. But I hated the new Dune movie. I didn't like how sterile and empty they made the palace, or the weird anus mouth design of the sand worms. Or the silly use of balloons to help lift harvesters. I very much didn't like how they made Lady Jessica an emotional mess, instead of being in control of her outward emotions, as she was trained to do.

They also screwed up the personal defense shields REAL BAD. The idea that the shields react to kinetic energy, so a fast moving project from a firearm would get stopped, but a slow moving blade would pass through. The fight near the end had people being killed by fast sword strikes by hitting the shields, it was just so jarring and lazy. They also completely misrepresented who and what the Sardukar are. Based on how many people loved the movie, I have an unpopular opinion. Though I found that most people who absolutely loved the movie hadn't seen the original movie, or read the first book, so they didn't know anything to color their impression.
