Dune (1984) is an old Sci-Fi movie about a book with the same name, made somewhere around the time as Star Wars and costed 10 million more, but turned out less popular and... well... I really don't want to be hard on Dune, I mean , the book is great and all, but man oh man was this all messed up. And I would have never expected that from David Lynch. Yeah... just gets better and better from here.
To start with, thank the maker that there is an introduction to explain why and what is going on, because I surely think that those who did not read the book would not understand a single thing in the movie , at all. That is probably the good thing, i don't know.
