Here's my theory on how this film was conceived: Lanthimos, Plemons and Stone (imagined in my head as three stoner roommates) were smoking weed and watching cartoons one night, and Plemons said to Stone: "What if you were like, an alien and I couldn't know it?" Then the three started riffing on the idea and laughing their butts off Beavis and Butthead -style, and decided on the spot to make a movie about it. They wrote down some ideas and the ending, and by the time they sobered up they realized they'd already signed contracts to make a movie. So Lanthimos got to work on the script, and in the process turned it from a bumbling stoner comedy to a dark look at the edges of modern society, but kept the original stoner comedy ending.
And that's what ultimately dragged this movie down for me. See, it turns out in the final minutes of the movie that Stone's character
was in fact an Andromedan alien, and Plemons' character had caught on to her. He was right about literally everything, down to the shape of the alien spaceship. Stone's character teleports back to the mothership, and decides that humanity's had its time, and basically instakills every living human on the planet. It is such a jarring, out of nowhere ending that's so completely out of step with how grounded the rest of the film is, that right as I realized it was happening I started going: "Do I kind of hate this? I do kind of hate this don't I? Yeah, I definitely hate this." This isn't presented as a comedy or satire in the vein of
Don't Look Up where this kind of thing would fit. The movie's an uncomfortably realistic, downright grueling examination of what happens when someone is no longer tethered to reality, and the damage it can cause. So when the movie decides to switch gears at such a late point, it feels like it actively undermines itself. It's like watching someone give an informative, well presented lecture about the health effects of fast food and the harm it causes, and in their closing statement chow down in a XXXL Bacon Blaster 9000. It just left a bad taste in my mouth, and made the movie feel disingenuous and half-hearted.
To my surprise this movie is actually a remake of a Korean film called
Save the Green Planet from 2003. I don't know anything about it, but the poster at least would suggest a much less serious, and more whacky film than Bugonia. It just goes to show that not every director's style is suited for every movie premise.
