Dune is a classic scifi novel

In the same sense that Forbidden Planet is a classic scifi flick. Both have become outdated in light of the advances in our knowledge since they were released.

With the problems with the Duniverse setting and the nature of the worms and the dependence of the plot on elements such as prescience and genetic memory, I'm wondering if Dune shouldn't be reclassified as primarily science fantasy.

I'm not saying that it's not a great novel. Only that I am less willing of late to suspend my sense of disbelief and that my enjoyment is thereby lessened.

Ah well.
