I agree with the consensus. This film stinks. The true plot is brusquely steamrolled over in order to force the emphasis toward a badly cast romance between George and Heather.
This type of butchery is very common these days. Look at most of the `original series' on the Sci-fi (sic) channel. Get a bunch of young and beautiful people into spaceships, fill it with flashing lights, a crotchety alien with a bony forehead and the personality of your uncle Irving, derivative dialog about `shields failing' and `re-routing emergency power', don't EVER have an original or though provoking story-line and voila you get the distilled pap that passes these days as science fiction.
Its unfortunate that style, special effects and sex-appeal are what now count instead of real dialog and story. The original Lathe of Heaven wasn't perfect, but everything about it, from the slow build-up of George's relation with Dr. Haber, to the philosophical discussions about righting the world's wrongs made for an engaging and genuine exercise in science fiction.
Big budgets, merchandising tie-ins, vapid music and a bland dumbed-down appeal characterize far too many productions these days.
