I knew this one Twilight fan who found it pretty hard to follow and dropped it early on. I myself am a fan of the original. Lynch's film is also fairly good, though that's the Lynch fanboy in me and not the Dune fanboy. Also loved Emperor: Battle For Dune, even though it isn't the most balanced RTS out there.
Are...are you insinuating that I'm a Twilight fan? D:

You, sir or madam, have done me a grave disservice! Apologize at once!
In seriousness, Dune isn't the only "classic" that I didn't enjoy. I liked parts of Snow Crash, for instance, though on the whole I found it somewhat bland and not nearly as cool as the fans insisted it was.
