Yea, I just got back from seeing it today at the local flea pit. Daughter struggled to stay awake.
Sound / score was great . Visually it looks good .
Walken did not fit as Emperor at all as already stated. Also , give him a haircut. Bloke runs the universe but cant keep his barnet in check.
Stilgar wasn't that militant in the book.
Time frame got totally screwed over , the time frame of 4 or 5 years in Dune got swapped to 6 months or similar.
Alia never appears , Hawat never appears .
The importance of The Sardaukar and how good they were as fighters . Cut out one of the scenes I love from the book where the Sardaukar are
By smuggling with Gurney and how they get humiliated by the Fremen.
Chani is totally changed as a character.
Paul's abilities and fighting skills aren't really emphasized , the fact that he trains the Fremen in The Weirding Way.
No mention of The Guild .
Nothing about the Crysknife.
Nothing about the fact that Chani and Paul have a son , Leto who dies.
So much missing. And yea, I know the time limitations of the book Vs film but still , characters underdeveloped and at the end I was like ' meh' .
