I'm with you mostly on the "really like" side. Sound all the way around is excellent. Little details like the horn blowing dust when they disembark from the ships on Arrakis are great. Salusa Secundus in the rain was great. The overall visual style is great. Casting was mostly great.

I just wish some of the sets were a bit more dense. The room for the Gom Jabbar scene, the Bene Gesserit walking back to the ship, cone of silence scene, and especially the palace fight on the stairs. Kinda gave my Sky Captain vibes.

I also don't like cutting the tension between Jessica and Thufir, although if Thufir doesn't end up under the Baron I guess I get it.
