Two Sci Fi movies that are incredibly fun and entertaining, but are really bad movies are "The Fifth Element" and "Starship Troopers." I remember reading that the second was originally going to be billed as "Robert Heinlein's Starship Troopers," but Virginia Heinlein threatened legal action for how they changed the story. Other than some character names, two totally different stories. But both are really fun to watch.
And so is John Carpenter's "They Live." Something hilarious is that South Park's Trey Parker and Matt Stone exactly choreographed their "Cripple Fight" from the fight scene in "They Live."

The book is semi-hated by the Left as being pro-fascism. They overreact, as usual.
