16. 'The Hangover Part III'
Most everyone that saw The Hangover Part II felt it was a pale retread of the original, but it made well over a half-billion dollars, making a third chapter inevitable. It follows the formula of The Karate Kid III, Super Mario Brothers III and Oceans 13 in that it takes the story back to the original location after a second chapter where the characters visited an exotic, faraway land. But even back in Las Vegas and without an actual hangover-induced memory lapse, The Hangover Part III still felt tired and predictable. You could almost see Bradley Cooper calculating how much money he was making per second during most of his scenes. It was so hated that even President Obama made fun of it when he appeared on Between Two Ferns. "You know if I ran a third time, it would be sort of be like doing a third ‘Hangover’ movie," he told host Zack Galifianakis. "Didn’t really work out very well, did it?”
