1) “Well, I Was Only Born Yesterday.”
You may have been expecting a huge action packed moment to take the #1 spot, but this scene in Avengers: Age of Ultron stands out as being better than all of those combined.
As tempting as it was to put The Vision lifting Mjolnir here (that was without a doubt one of the most surprising reveals in this year’s superhero movies), this quiet final moment at the end of the sequel between The Vision and his “father” Ultron topped that, and ended with a stellar piece of Joss Whedon dialogue as the newest member of The Avengers wiped away the villainous android in an ambiguous enough way to ensure that Marvel can always bring Ultron back if they so choose.
