Actually, I could neverget past "Dune" as a standalone. It always seemed to myself that the work was written to be a sole masterpiece, but that commercial pressures made Frank Herbert extend the series. Heck, Dune Messiah, so far as I can tell, isn't even written in the sme narrative style and brings into being constructs that seemed misplaced beside Dune. I've tried touching the sequels but was always somehow repulsed from them. I just have difficulty seeing them properly connecting with the first great "Dune".
