After my recentMCUrewatch, I realized just how important the lowest grossing Avengers movie actually is.Avengers: Age of Ultronwas released on July 06, 2025, andfailed to live up toThe Avengersjust three years prior, both critically and financially. Despite all of that, looking back on how farthe MCU timelinehas come, it’s impressive just how much heavy liftingAvengers: Age of Ultronactually did for the universe.
Marvel has a big release slate in 2025 and beyond, but it is nice to look back on when the universe was trying to find its footing. There were growing pains trying to figure out what direction to take it, but when Phase 3 hit, and the MCU saw success after massive success, all the groundwork laid before is a big reason why.Avengers: Age of Ultronis one of those movies that had to weather the growing pains, and revisiting it reaffirms its place as not only one of the best MCU movies, but one of the most important.

Astonishingly, A Billion Dollars Was A Comparative Disappointment
WhenThe Avengerscame out in 2012, it shattered all expectations, making over $200 million in its opening weekend for a then record. It then went on to make over $1.5 billion worldwide, cementing it as one of the high grossing movies of all time.Avengers: Age of Ultronactually made less in its opening weekend, which typically doesn’t happen with Marvel sequels,bringing in $191 million to an eventually worldwide total of $1.39 billion.

That number stands out even more afterAvengers: Infinity Warmade over $2 billion, andAvengers: Endgamebriefly became the highest grossing movie of all time with over $2.7 billion worldwide. One movie had to be the lowest and that fell toAvengers: Age of Ultron. Despite the financial downturn from The Avengers, the sequel’s box-office is still incredibly respectable as it sits asthe fifth highest grossing MCU movie, behind the other Avengers films andSpider-Man: No Way Home.

It Set Up So Much Of The MCU Going Forward
The Shockwaves Of Ultron’s Attack Are Still Felt In Phase 5
At the time, one of the big criticisms ofAvengers: Age of Ultronwas that it tried to set up too much going forward, with various members of the Avengers splitting off to set up their own films. Looking back on it now, it actuallyset the stage for a lot that the MCU would explore in Phase 3and the lead-up intoAvengers: Infinity War, with arguably the most important being the initial seeds being planted forCaptain America: Civil War. In fact, most of Tony Stark’s motivations going forward come from his vision that Scarlet Witch showed him.

I’ve always believed that Ultron would come back, and reports that Marvel Studios is reversing his apparent demise is one of the best MCU decisions.
Although the tone of the film ended up being much different, Thor’s motivations to return to Asgard to stop its destruction sets upThor: Ragnarokalongside Bruce Banner deciding to leave Earth at the end of the film.

Age Of Ultron Is Better Than People Remember
Time Has Been A Lot Kinder To The Avengers' First Sequel Than You Might Imagine
As time goes on, I personally feelAvengers: Age of Ultronis one of the strongest MCU movies overall, at least when it comes to Avengers films. It easily looks the best of the Avengers franchise, as well, with some of the most gorgeous looking CGI the universe has ever had. What really helps elevateAvengers: Age of Ultronis all the interactions the characters have with each other. They all feel distinct, and the party scene is one of the best things to ever come out of the MCU.

The biggest flaw ofAvengers: Age of Ultronis the titular villain. The trailers for the film promised something much darker than what came before, but the final product felt different in tone, especially Ultron, whose personality was essentially modeled off Tony Stark, but it was his actions in Sokovia that helped shape some of the conflicts in future installments.
