The movie was by the same director who did "Parasite," and deals with similar themes of class warfare. (I think it's only a remake of "The Wizard of Oz" in the sense that any movie in which several people team up while on a journey to do battle with someone is a remake of "The Wizard of Oz.") The TV show expands on the world in which the movie is set, and I think it does it pretty effectively, especially in the first two seasons.
Kevin hates everything, so take what he says with a grain of salt -- and my email address is "trainman," so take what I say with a grain of salt, too.
