Endgame follows the remaining Avengers as they figure out how to move forward after the events of Infinity War, in which the intergalactic tyrant Thanos acquired all the “Infinity Stones” and destroyed half of all life in the universe—including Black Panther, Doctor Strange, Spider-Man, and, crucially, Groot.

The films are ranked from worst to best based on my opinion (with input from my Quartz colleagues), but I also included Rotten Tomatoes ratings and blurbs about how relevant each film’s plots are to Endgame. Many of these films are eminently skippable, but the top 10 are certainly worth watching for anyone who likes superhero movies.
