@clacke I like the 1984 version more because it was bolder visually, and played out more like a thriller than an action movie, which does feel closer to the book where action scenes are kind of abstracted away. The 2021 version is visually impressive, but less aesthetically daring and a tad too fighty, which dissipate a little the constant paranoia developed in the book that everybody is feeling at all times at this level of political power.
I also agree with @tipjip about Jessica who doesn’t represent the frightening Bene Gesserit cult very well.
I’m still looking forward to the subsequent Villeneuve movies.
