There's no novelty here. After the "poignant" commentary on Capitalism by the (surprise! Korean!) film Parasite, this was a predictable and uninspired spin-off. And before Parasite there was Snowpiercer, another commentary on Capitalism and the wealthy elite.
I'm all for intelligent and thoughtful commentary of any type but the crescendo of overacting and the incessant one-upmanship of "shocking" scene after scene in ever-more contrived and unrealistic contexts reaches the point of saturation very quickly.
In fact, it has the structure of a video game timeline, forced into the format of a film. What's the next challenge? What's the next escalation? Very formulaic.
