Query: Brilliantly horrible

Plan 9 should be required viewing for every movie fan. Don't bother watching it alone-- you need to be with family and friends, and challenge each other to identify bizarre dialogue, ridiculous "plot" twists, monumental errors in consistency (the same scene will switch from darkness to light several times, to cite but one example), and spectacularly inept special effects. (My favorite is the tombstones that wobble when touched by a woman's nightgown.) "Can you prove it didn't happen?" and similar lines deserve to be heard by all.
