I watched both Lynch's and Harrison's movies, I've read the book itself as well. And I think that the older movie is much, much better, despite of its few disadvantages.
Harrison's film is longer and contains more facts from the novel, but - real paradox - it is washed out of Dune's specific climate and atmosphere. Lynch captured it much, much better. It is felt from the start to the very end.
Other things, that I don't like about the newer Dune movie:
- The acting in this film is mainly a big mistake, mostly due to the fact, that many characters (including Paul) do not reflect their actual personalities from the book
- This film is simply hollow, and, like I said, it has none of the Dune's climate. It is boring as well.
- Costumes they decided to use in this film are one big tragedy. It seems to be a detail, but when I am forced to watch this parody through entire movie, it ruins the whole. The only costumes, that are not a disaster, are the stillsuits, and maybe Atreides' (and Emperor's) uniforms. All others are merely idiotic. Hawat's costume is ridiculous. Sardaukar? When I saw them, the thing, that came to my mind is "OMFG. What is that supposed to be, Picasso fanclub meeting?". Oh, and the Harkonnen, who look like a parody of Japanese samurai. Let's not forget about the Guild members, who do not only look stupid, but behave so as well, waving idiotically with their hands when speaking.
Lynch's movie is much better, although it misses many facts from the original novel. Those that are most important to the main plot, were shown, though. However, there are few things, that I compain about, as well.
The first one is the general appeareance of the Harkonnen in this movie. They are completely disgusting and horrible. They were, of course, cruel and barbaric in the actual novel, but not obscene.
The second thing is the cat's milk as Hawat's antidote.
The third thing is that strange idea with voice-pistols.
