The heartplug was a great stylistic addition by Lynch. I'm the biggest Herbert fan ever, but I just don't understand the Lynch Dune hate. True, it wasn't word for word taken from the book, but I think Lynch got the awesome Dune noir down pat. Even though the Sci-Fi channel miniseries were more technically accurate, overall, they missed the mark, big time. JMHO. edit: The Alan Smithee cut is worth having if you can find it.
