Its one of those iconic 80's swords and sandals/science fiction blend movies and beloved by many. We can understand why, but this was a massive failure that likely cost the genre decades of great movies until the LOTR Trilogy.
So Krull is one of the most expensive movies of the 80s and fails on so many levels. You've got the classic inaction in action (nothing happens during action sequences), the choreography was done by Stevie Wonder, and the effects and sets are so overly impossible to do that they end up looking like 2nd grade paper Mache. The wire work is only worse in Spider-Man: Turn off the Dark. The costumes are atrocious and prevent the actors from actually engaging with each other or the scene itself. Its a mess.
While all of that may sound like Red Sonja or Dune, Krull falls more into the Flash Gordon's of bad movies. Its loved because of the cheese and the failures. Add in wizards living with kids in rocks, a doofer for a hero, forgetting to use The Glaive, the cyclops who can see less than the blind guy, plot advancing by "I know a guy who knows a guy", Star Wars similarities and the rules of the universe make this a classic stinker. Krull is one of those unique films that is too long but if you cut it down it'd only be worse. It's not anywhere near a Hall of Fame discussion but shouldn't be missed by anyone except people who have stuff to do, like laundry..
