Query: It ruined me!

Quite frankly, Frank Herbert has done me a serious disservice. Since reading Dune, I've not been able to enjoy any science fiction work to the extent I used to! Nothing I read or see compares to DUNE, and yet I am always forced to compare. Dune is THE standard by which all other readings will be judged. It is the best.
