Age of Ultron: 8 Ways The Avengers' Quicksilver Beats X-Men's
1. It's Pietro, Not Peter
What this truly boils down to is the MCU’s fidelity to the original character. While some fans consider comic-book movies to be a superior step up from comics that can be cheesy and juvenile, one can’t really enjoy a Marvel movie without being able to face the fact that Stan Lee and friends kind of knew what they were doing.
From the inclusion of Scarlet Witch to a better retelling of his backstory, Whedon appeared to have a deeper understanding of the character of Quicksilver as adapted from Marvel Comics. While X-Men’s Quicksilver was certainly well-written, amusing, and downright cool, he was hardly Pietro Maximoff, something perhaps realized by Singer and co., who renamed the now-American teenager ‘Peter.’
Quicksilver in the comics is a moody, serious, anxious hero with a less than comical disposition, and heroically ambiguous at best, a character profile aligning more closely with Marvel’s depiction than Fox’s.
While there is no inherent goodness in being more faithful to the source material, the MCU hits the mark better because of their fidelity anyway: while only a twenty-minute film character, Quicksilver has decades of comics under his belt, and is an accordingly complex character. By attempting to depict more of the dimensions of Quicksilver as seen in the comics, the MCU, compared to Days of Future past, truly gives the character his due.
