Lots of people and critics hated it, but I loved it. I had read the books so I wasn't confused about the characters in the movie, but I saw it in the theater and they handed out a printed list of the characters and brief description of each to try to help people understand. Yeah, it had its flaws - there was no mention of weirding modules in the books, for example - but to me it captured the weird
feel of the book well, and certainly better than any other Dune treatments that have come out since then.
