6 Underground is cartoonishly raucous explosion porn from mayhem maestro Michael Bay that feels like a film that was made over a decade ago and was just somehow recently unearthed by Netflix. It’s a testament to star Ryan Reynolds and his seemingly effortless charisma because without him the movie would have been a snow-blind mess.
Overstuffed with countless car crashes and numerous “booms” and “louds,” 6 Underground owes pretty much any watchable aspects to Reynolds and his charm. And even with Reynolds, the film is overlong, easily trespassing into tedium at the halfway point.
The premise, in itself, feels very Avengers-esque, in the sense that it centers on a rogue team of specialized operatives who will happily cross borders and waters to right egregious wrongs. But 6 Underground is an argument both for and against the Sokovia Accords, as Reynolds plays a Tony Stark-level billionaire genius who’s decided to fake his death, become a ghost, and pull off grand vigilante-style heists and hits with operatives he’s recruited (and ghosted) in order to punish powerful evildoers (in this case, the dictator of Turgistan).
