Dune

I can't argue that Dune is a major foundation for Sci-fi and that a big part of my critic is based on things that didn't used to be done at the time. In the overall I liked the book but I will talk about what was lacking.

The book is interesting and the universe is full potential! Potential that sometimes I found unexplored. The spice for instance, or the sandworms. We know they are the most important parts of the story but were rarely used for the development of the story. For example, Paul riding a sandworm had no impact on the main story whatsoever.. Which leads me to my next point ;

Paul Atreids. Paul is the definition of the Chosen One trope on steroids making him way too over powered and therefore making the audience easily detached from the character. The event I mentioned earlier, riding the sandworm, even if it was Paul's ultimate test to be seen as a Fremen, was done with no struggle whatsoever.
I loved Paul at the start of the book but the more the story developed the more I found myself hating Paul. I was wishing he'd get killed at the end by Feyd-Rautha which would've given the story a kind of interesting/unpredictable ending.

But in the end I'd say that my major disappointment with this book is how predictable everything is. The more the book progresses the less you'd feel tension for the characters as you realize that events never deviate from the predictable path.

Many events were also pointless or had no impact on the story, for instance, again the sandstorm riding, Gurney believing Jessica was the traitor..
