Part of what makes the Marvel Cinematic Universe as successful and as popular as it is, is the shared universe aspect of it. Every movie from Iron Man to Spider-Man: Far From Home, fits as a piece of the greater puzzle, allowing for incredible crossover events, and unequaled storytelling potential.
However, aside from playing its part as a chapter in a larger narrative, each movie has to work as its own stand-alone story. The links between every movie and the wider universe are what make the franchise so special, but without the individual films being able to work on their own, it simply wouldn't have the same effect.
Within the Infinity Saga are 23 stories to be told. Some, naturally, are bigger and have more impact on the MCU than others, and some are simply better than others. As with any good movie, the stories are often only as good as their endings, and the Marvel Cinematic Universe has some simply stunning cinematic climaxes to boast.
From unique battles to iconic scenes, huge revelations and sheer aesthetic joy, some of the greatest MCU moments have come at the very end of these movies.
