All that is however background, for what really matters - the story. A young-adult-esque adventure detailing the journey of heroine with a firm basis in mythology. The three siblings trying to lead the heroine astray with wealth, compassion and intimidation, respectively, is just one example of a mythological element to the story. Many reviews states that Kunis' Jupiter is a passive protagonist, but that couldn't be further from the truth. She makes active choices and eventually chooses her own way, the fourth path, and she changes along the way - notice how she goes back to life she lived before with renewed perspective at the end (perhaps the biggest irony of all). She needs a little help from Mr. Virtue (Tatum) on the way, but she eventually makes the right choice. The reason why you see the characterisation as flat is because it is - all the characters just represents an attribute, because Jupiter Ascending is a mythogical allegory first and foremost. A didactic tale, if you like.
While being that, it provides a good dose of humour as bizarre as the rest - the scene where Kunis pulls a sanitary towel from the glove compartment of the car and put it on Tatum's gunshot wound (only to have Sean Bean pull if off later and look puzzled while standing with it full of what only looks like menstrual blood) is just one example, and action sequences as thrilling as anything - Tatum's hover-boots may not exactly be original, but they're definitely the most exciting version of the idea. As for the acting, Kunis and Tatum has some real chemistry between them, and carry the film well. Eddie Redmayne's over-the-top performance will divide opinion, but is exactly the kind of villain a film like this needs. Someone who wants to be menacing, and maybe at first impression is - but just turns out to be a patethic loser who has no power once you see through him.
The story is The Hero's Journey, we get it, we've seen it before in Star Wars, The Matrix, and everything else. I'm struggling to see how the temptations presented by the siblings are inherently mythological elements. Jupiter makes active choices, she is not completely passive. She is, however, a complete damsel in distress. She does nothing to help herself other than run away and call for help. She even has a chance to off the villain and decides to walk away. She is weak. She may be "powerful", but the only part of her that is strong is her choices. Much of her story makes literally zero sense - what the hell was the point of the bees? They never reappear, they have no significance other than helping Jupiter to believe the truth of her heritage (something which a bunch of aliens, spaceships, and bounty hunters could easily have done). And I'm all for mythological allegories, but that does not mean that your characters should be bland and forced.
Mila Kunis is absolutely flat throughout the whole movie. It seems as though she received no direction from the filmmakers. Case in point: the scene at the end of the film in which she runs around a factory that is crumbling and exploding. She's running for her life. This is it. If she doesn't survive, it's all over. Look at similar scenes in films like Aliens or Jurassic Park, where the heroine runs away from certain death. Those actresses are tripping, stumbling, gasping for air and running into walls. They are selling that perilous moment. Mila Kunis looks like she is jogging at the gym. It's disgraceful. Channing Tatum is one note, but likable. I enjoyed Redmayne's whisper voice, but the yelling moments were awkward at best.
There is very little humor in the film. It's as melodramatic as can be for the most part. There are so many moments where a simple joke would have gone over miraculously, but the Wachowski's are far too serious for that kind of thing. The love story is appalling in its insincerity. We're
told that Jupiter always choses the wrong man. Ok, but we don't see that, so why do we care? We're
told that she loves Tatum but we're never given any reason other than that she likes being rescued by hunky, unavailable guys and has a strange canine fetish. We're
told that they're meant to be because that's what the plot demands. There is not one shred of believable romance in the whole film. I believe Tatum loves Sean Bean more than he loves Jupiter.
Also, why in the hell are a bunch of badass dinosaur/dragons kowtowing to that sniveling little brat?!
