Just to clarify, 'They Live' and 'Truck Turner' both come with my highest rating, if only for the quotable lines alone. They don't take themselves seriously, which is exactly why they succeed...
But, the
worst films I've ever sat through in the theater are absolutely:
--Dick Tracy (walked out),
--Waterworld (gills, really???), and
--The Island of Dr. Moreau (the Brando/Val Kilmer one)
Each so uniquely horrible in it's own way...
