Dune

Dune has some interesting concepts eg travelling using foldspace and prescience, but in general the theme is retrograde (for a SF book).It bored me to death. It is probably one of the most banal works ever done and worse, it has pretensions of sophistcation.

Being an atheist, I found references to religion, the "arrival of a messiah" to be plain offensive. Also, for a universe set in the distant future, the societies are more medival than "futuristic"(even considering the ban on all thinking machines). This future has emporers, dukes, barons et al. Free society I guess is an alien concept. I wouldn't want to live in such a feudalistic society.
