In the mid-2000s Marvel was in trouble. Comics were a thing of the past and superhero movies were at a crossroads. Rights were scattered across a number of different studios making it difficult to wrangle any of these heroes into a single franchise. Then Marvel Studios had the crazy idea to attempt to bring some of what were then considered B-list heroes under one roof to launch a new cinematic universe. It was unprecedented and no one thought it would work—especially by anchoring this massive undertaking with a nobody like Iron Man. But, the Robert Downey Jr.-starring film was a hit, and history was made.

Now, after 23 movies Marvel has officially concluded what it calls its third phase of its Cinematic Universe with Spider-Man: Far From Home. Along the way, the MCU has far surpassed other major franchises like Harry Potter and the Lord of the Rings/Hobbit series in terms of box office numbers. And though at this point the Disney property has crafted a reliable superhero movie formula, not all of the MCU movies are created equal. Here they are ranked from worst to best.
