I started in the middle, jumped around, and then went back to watch the early ones for completions sake. If I had watched them in order I probably would've given up because the movies of the first five or six years aren't very good for the most part. I've found that watching more of the movies enriched the overall universe storyline but most of the movies are good enough as standalones that viewing order isn't essential and you won't miss anything by skipping the bad ones. I'd consider the following to be the ones most worth watching: Captain America: The First Avenger Guardians of the Galaxy (if you like this one, then also watch the sequel) Ant-Man (if you like this one, watch Ant-Man and Wasp too) Spider-Man: Homecoming (if you like this one, watch Far From Home too) Thor: Ragnarok Black Panther Captain Marvel And the four Avengers movies and Captain America: Civil War, which are the big crossover movies. You should probably also watch Captain America: The Winter Soldier because most people love it and I seem to be the only one who thinks it "meh."
