Will there ever be a version of “Rebel Moon—Part 2: The Scargiver” that makes the movie and its franchise seem essential? Director and co-writer Zack Snyder has already tried to whip up his fanbase by teasing “R-rated” versions of the first two entries in his ongoing “Star Wars” ripoff cycle, a lifeless homage to that other IPed-to-death sci-fi series. The well-covered struggle to release the Snyder cut of “Justice League” notably improved what was only ever a passable super-programmer. It’s also established an unfortunate precedent for how “Rebel Moon” is now being advertised, as a victim of its own release strategy.  

Unfortunately, while I can’t review a version of “Rebel Moon—Part 2: The Scargiver” that I wasn’t allowed to see, I can say that I doubt more (or just more extreme) violence and sex will improve this joyless expansion of the previous movie’s Kurosawa-sploitation space opera. The shortcomings that kept the first “Rebel Moon” from ever taking off are still apparent in its sequel, particularly Snyder’s disinterest in his actors’ performances as well as this movie’s vast array of bland visuals and flavorless dialogue. Like the last one, the latest “Rebel Moon” looks like it was rushed through production to compete with whatever “Star Wars” series is now streaming on Disney+. The Snyder faithful may see something in “Rebel Moon—Part 2: The Scargiver” that the rest of us can’t, but that doesn’t make this tired sequel any less puny.

Previously on “Rebel Moon”: A group of misfit rebels banded together and seemingly defeated the Imperial Space Nazis, led by the goofily accented Regent Balisarius (Fra Fee) and the lanky rage-case fascist Atticus Noble (Ed Skrein). Noble was killed at the end of “Rebel Moon—Part 1: A Child of Fire,” but even the end of that movie hinted that he wouldn’t be dead for long. Sure enough, he’s back again and now angry enough to retaliate against the smalltown farmers of Veldt, an idyllic moon with Smallville-style fields of space-grain, Oshkosh B’gosh catalog-ready space-farm children, and “Asterix”-type longhouses, too. 

Who will save the people of Veldt, represented here by the young and ripped hunter Den (Stuart Martin) and the older but also chiseled Hagen (“A White, White Day” star Ingvar Sigurdsson)? The same motley crew as last time, still led by the scowling ex-general Titus (Djimon Hounsou, the generically mysterious Kora (Sofia Boutella), and her unconvincing love interest Gunnar (Michiel Huisman), the last of whom is also from Veldt. In case you’re wondering what else has changed since the last “Rebel Moon”: there’s a scene where our heroes share what they’re really fighting for, which they emphasize through momentum-throttling, voiceover-smothered flashbacks.
