Very very boring Oh man. Good god. That was my reaction several times throughout this film, and not in a good way.
Within the first minute I was already dreading it, as the opening narration mentioned some generic ruling star empire where "a thousand kings ruled uninterrupted", which is a lot like a chain-smoking fat man with a drinking problem saying he's going to live to be 150. Or maybe it's just being cheeky and there were actually hundreds of kings ruling over the course of a couple of years, being constantly deposed or assassinated every few days.
This bothered me because this felt like a lazy foundation from which to start a whole new science fiction universe, and my feeling was correct.
This movie spends its first hour just on worldbuilding, except that the world it's building is bland and boring. This could easily be transplanted into Star Wars or Warhammer or any other major franchise and almost nothing would have to be changed. And this isn't in a good "timeless classic" way like the story of Seven Samurai (an obvious inspiration) is.
Instead it's because the story's setting is so empty it's like a blank scifi RPG template was picked and Zack Snyder never actually bothered to fill out any of the details.
There's tons of comparisons made by reviewers to Star Wars, and the knowledge that apparently this was originally meant to be a Star Wars film that Disney passed on (a rare Disney W). Any resemblance to Star Wars is purely superficial; there's almost nothing here.
The original "Star Wars" had a similar initial setup of a big evil empire and a plucky band of rebels building up a resistance against them. As well, it had many different things and people happening around it, references made to things, people, and events that clearly were important to the world we were seeing, like Obi-Wan, the Clone Wars, the Jedi being defenders of the Republic, the Force, Jabba, the Imperial Senate, all these things were brought up in the very first film and treated with a sense of having some very clear importance to the story as a whole.
There's nothing like that here beyond the absolute bare minimum of words to fill it in. The "Imperium" rules from its "Motherworld". They were ruled by kings, then their last king was assassinated and an evil psychopath named Balisarius took over or something. Now they are cartoonishly evil and they literally rape and murder and destroy entire planets for no clear reason. They raped murdered and destroyed Kora's planet and kidnapped her as a kid to raise her as a soldier for the Imperium until she deserted.
That's it. That's pretty much the entirety of Rebel Moon's world that it took 45 minutes to set up.
Without anything else to it, you'd imagine there would be some interesting characters or wild action scenes to entertain with, but there aren't. Everyone has the same sort of bland flattened affect of an RPG NPC waiting for you to level up enough to unlock their backstory sidequest. Some of them don't even seem to have names until many scenes later when another character mentions their name out loud.
None of the action scenes are in any way memorable or exciting, as at best they could be described as shot "functionally", except apparently Zack Snyder's gimmick is random slow motion, there's constant instances where the action will suddenly go into slow motion for no reason.
The slow motion didn't bother me as much as it apparently does other people. What did bother me was how the camera kept randomly unfocusing during scenes, blurring for no reason, or suddenly going into a sort of fisheye lens appearance, or one shot of Kora and The Farmer Whose Name I Forgot, where suddenly the Farmer's face started to blur while Kora's remained sharp and in focus.
All of this would be laughable if the entire film itself weren't so BORING. Pretty much everyone looks and sounds miserable, even in scenes they're supposed to be feeling triumphant in, and the only actor who seems to be putting any real effort into their work is Ed Skrein, which is somewhat amusing because ten years ago he played Daario Naharis in season 3 of Game of Thrones and then was replaced by Michiel Huisman (also in this film) because supposedly they didn't think his acting skills would've been up to par for what they had planned with Daario later on (which turned out to be mostly nothing).
If you told me this was a film that was written, directed, photographed, and edited all by first timers, I would believe you. It has almost no redeeming features unless you are the kind of person who likes looking at flashing lights and sweaty people, in which case there are plenty of other movies that have that that aren't as BORING as this.
