Matthew N’s review published on Letterboxd:
“Little things into big ones.” Density. Pure-blooded maximalist cinema. What Bay has created here is the absolute conclusion to his style of filmmaking. The “narrative” completely takes the back seat to the action, which is exhilarating. It’s this pulpy, idiosyncratic fever dream in which you must let the adrenaline rush engross you. It frankly doesn’t matter what the film is “about”. With 6 UNDERGROUND, Michael Bay births a series of images in sound and color that protrudes upon itself. His auteurist vision won’t work for many, but if you’re sold on it, then you’re in for one of the most blatant, insane, and fucking awesome films of the decade. Glorious. Staggeringly, inexplicably beautiful. The end of the world in slow motion.
