The best thing in the first movie are the special effects but it's lacking a lot when the discipline and characters are involved. The fisrt book is much better but it's not perfect, it lacking some things but it's has been written about 60 years ago. The science and tehnology have been evolved a lot since them and every writer can have some new ideas (not exactly better ideas) when writing science finction, and some guy tries to analyze the life from Dune and the science involved on Arrakis. Of course, they are some ideas and they are compared with what we know now. Life itself can be very different from what we know in these moments and it's not involving Dune itself.
You can watch the video and go reading the books again. Books are much better that movies, so you should read and think not just watch and laugh.
