Hollywood films frequently employ what’s called the “high concept” approach. That’s when you can describe the gist of the movie in a sentence. For the original Ghostbusters, for example, the high-concept sentence might have been: “A comedy in which geeky paranormal scientists use high-tech gadgets to catch ghosts and save the world from an ancient evil being.” Pretty compelling!
For Downsizing, the high concept pitch probably was something like this: “The world is changed when scientists discover a way to shrink human beings to five-inch size in order to reduce humanity’s carbon footprint and allow the tiny people to live like kings.” That sounds pretty interesting, too, and like Ghostbusters would allow for lots on great special effects, too.
But where Ghostbusters built great ideas and characters, like Mr. Stay-Puft and the controlling EPA twerp, into the plot and made the movie a classic, in Downsizing the premise just sits there, thrashing around in search of an identity. Is it a comedy, or a serious approach to global warming, or a treatment about how humanity is ultimately frivolous, caste-bound, and uncaring? Potentially interesting notions of how the big-people world and the little-world world would interact get raised and then vanish without a trace. Characters come and go, seemingly at random, stereotypes bizarrely intrude into the plot, and by the end of the movie, when a five-inch Matt Damon is beating on a drum on the shores of a Norwegian fjord with a band of hippies who are preparing to go underground to save the human species, you’re scratching your head and wondering what the hell the movie is really supposed to be about.
Downsizing shows that the initial high concept only takes you so far. The special effects are good, and the weird twists and plot holes will give rise to lots of after-movie analysis, but this film is a quickly forgettable dud.
