The Marvel Cinematic Universe has had its ups and downs, but there are a lot of perfect and near perfect films to come out of it. It is hard to pick the best because <em>Iron Man</em> is the one that started it all, and then <em>Avengers: Infinity War</em> and <em>Endgame</em> almost feel like one big continuous movie. If I was forced to truly select what the best MCU movie is, I would have to go with <em>Avengers: Infinity War</em>. It brings together all of our favorite heroes in an unexpected, exciting, but also devastating way. That ending is an emotional moment that will likely never be topped in this franchise.
