11 Most Dumb MISTAKES The MCU Made

From Tony Stark's long list of catastrophic screw-ups to the split-second choices that decided the fate of trillions, we're breaking down every avoidable disaster across the Infinity Saga and beyond. Each mistake gets scored on our official Danger Scale, rated out of 10 based on how dangerous it was, the fallout it caused, and just how mind-numbingly stupid it really was. We're talking Iron Man 3 and the Mandarin, the terrifying EDITH glasses and Mysterio, the birth of Ultron, the Avengers' baffling refusal to ever call each other for backup, Thor Dark World, Winter Soldier, Steve Rogers and the Mind Stone, the Battle of Titan, Thanos, Doctor Strange, Star-Lord's infamous meltdown, the entire chaotic plot of No Way Home, and the messy scattering of heroes after Endgame. Featuring Quicksilver, Scarlet Witch, Peter Parker, Nick Fury, Vision, the Guardians of the Galaxy and more, this is the ultimate Marvel video essay for anyone who loves picking apart MCU logic, plot holes, and the wild what-ifs of the Infinity Saga. Which blunder do YOU think earns the only true 10 out of 10 on the Danger Scale?
