It should simply be left behind. I haven’t sought out the novel this film adapts; I've never noticed it available, and I question whether it will ever appear in Portuguese bookstores. Space-based stories aren't generally to my liking, but I can appreciate quality when I encounter it. And there wasn't any discernible quality here. The screenplay is completely nonsensical: we’re presented with a villainous galactic empire (clearly influenced by “Star Wars”), overseen by a despot (how original), and a rebellion fighting for democracy and freedom on an arid, desolate planet. The complication arises from the fact that this planet is the only place where a hallucinogenic drug—essential to the economy and operation of that empire—can be grown. Films directed by David Lynch aren’t universally appealing, and while I enjoyed his previous work ("Blue Velvet" and "Mulholland Dr." are, in my view, among his finest), I don't believe he was suited for science fiction. He possesses a highly visual and stylized directorial approach, and combining that with special effects, an odd setting, and an even stranger narrative proved to be a poor combination. I also have reservations about Dino de Laurentiis’s involvement… most of the films he produced—at least those I've seen—haven't particularly impressed me. Even so, I am certain that the project’s potential and the collaboration between these two figures secured a substantial budget and attracted actors to participate. However, Lynch seems uncomfortable with the source material, and beyond some visually striking moments that reflect his signature style, he doesn’t offer much more and struggles to effectively direct the performers. I suspect he's aware of this himself. Furthermore, the film’s poor reception from critics and disappointing box office performance contributed to its obscurity; it’s now conveniently forgotten. The cast, overall, is rather underwhelming, particularly considering the budget and the director and producer’s reputations. Sting, the musician, appears in the movie, but he's not an actor, and his performance feels perfunctory: he simply delivers his lines and shows off. The scene where he appears nearly unclothed is, to put it mildly, absurd. Patrick Stewart and Max Von Sydow are relegated to minor roles when they could have potentially done more with their talents. Virginia Madsen doesn’t convince, Kyle MacLachlan was a miscast choice, and the remaining actors settle for mediocrity. The film features stylized cinematography and numerous stylistic flourishes that would have been more successful if the movie itself weren't already so far-fetched and imaginative. The visual and special effects aren't always convincing, and the sets and costumes are, at the very least, questionable in their design. The soundtrack is quite grand, but given the general lack of quality, it feels overly pretentious for the film it accompanies.
