In a movie that's full of popular superheroes and teasers about the Marvel Cinematic Universe's exciting future, one of the biggest surprises in Avengers: Age of Ultron is just how much love Clint Barton, a.k.a. Hawkeye, received. Director-writer Joss Whedon certainly made Hawkeye an impressive archer in the first movie, but this follow-up does an excellent job humanizing the marksman.
Who is Hawkeye and why should you care about him? That's a question the first movie failed to answer. The Avengers showed he has phenomenal aim and some cool trick arrows, but aside from that, he was just Black Widow's friend and the guy who was unlucky enough to get brainwashed by Loki. By the time Avengers: Age of Ultron opened in theaters, he was the only current Avenger to not receive a proper amount of insight. Thankfully, Whedon fixed that by subverting just about everyone's expectations of the movie. Sure, it still has a fast pace and almost always finds a way to throw action and comedy in there, but the look at Hawkeye's personality and his life takes us out of all of the seemingly surreal craziness and makes things far more relatable. Suddenly, we get to see what it's truly like to be a "normal" human on a team full of powerhouses and geniuses.
Hawkeye's role technically isn't "important" compared to Captain America or Iron Man when it comes to the bigger picture, but his arc gave us all such a better emotional connection to the character and it made him infinitely more likable. It's cool he can shoot an arrow absurdly well and has a variety of pretty awesome trick arrows, but now when we see him in Captain America: Civil War, we'll know the guy firing those arrows isn't just some generic fellow who occasionally cracks a joke or two.
