C.S. Lewis is often quoted in A Grief Observed, “…pain insists upon being attended to. God whispers to us in our pleasures, speaks in our consciences, but shouts in our pains. It is his megaphone to rouse a deaf world.” The last time fans of the Marvel Cinematic Universe checked in with “Earth’s Mightiest Heroes,” The Avengers, they had taken the ultimate blow. In 2018’s Avengers: Infinity War, their foe, Thanos, snapped his fingers turning half of the entire universe’s population to dust. Everyone on every planet in every galaxy lost someone.

If the Marvel franchise were reminiscent of the action/sports movies of the 1980’s, our remaining heroes (comprised mostly of the original 6 from 2012’s The Avengers) would engage in an exhilarating training montage, find Thanos, and punch him in the face even harder than ever before! So perhaps the biggest surprise in the much-anticipated Avengers: Endgame, is that the villain in about two thirds of the movie isn’t one you can punch at all. It’s grief.

In Infinity War, the Iron Man that started it all, Tony Stark, was forced to hold a teenaged Peter Parker, his budding mentee and pseudo-son, in his arms as he faded away. Black Widow, who had finally allowed a group of people to become her family, had to watch it all come crumbling down. The Mighty Thor worked tirelessly to forge a weapon to defeat Thanos only to come up torturously short instead getting a front row seat to the finger snap that caused the genocide. Captain America has always been a little different. He is all too familiar with the cost of war. What we walk into with this movie is an exploration of grief from many different angles.

Black Widow throws herself into her work, trying her best to keep a grasp on what was. Cap dives into helping others process their grief harking back of his visits to veteran support groups in Captain America: Winter Soldier. Thor, having had losses building up across several movies, had all of his hope for a brighter future riding on him being able to take out Thanos. He is coming completely unglued from the Avengers team, from his responsibilities as king, and his own health. Meanwhile, Stark, the team’s futurist, has embraced the present to build something new. Anyone who has felt a loss will likely relate to one of our heroes’ forms of coping. Grief works itself out in so many different ways, and there’s really no perfect script to handle it.

Naturally, in the world of comics, the bad guys never triumph for long and evil is rarely afforded the final word. In the midst of their grief, a tiny light of hope comes along as the film launches into another wild Avengers adventure. Much like in Infinity War, we get to see new combinations of characters interacting and many memorable moments being created. Endgame is a gigantic movie with a runtime to match. Clocking in at a little over three hours, hardcore fans will be settled in for every second, but it will challenge the patience of fans on the peripheral. Hopefully, casual fans can hang in there, though, because the climax is nothing short of cinematic history unfolding. The final battle of this film redefines epic.

Yet pain insists on being attended to, and for those who have been following this franchise for the last 11 years across 22 films, there is going to be pain associated with Endgame. It very much is the end of the Marvel Cinematic Universe as we know it. Of course, the film sets up plenty to be explored in the future with Disney’s streaming service already promising limited series starring some of our favorites, but until Comic Con or D-23 (Disney’s annual convention) later this year there are no current plans announced for a Phase 4.

This is the end and it feels like it, but what an end it is! Endgame is filled to the brim with threads and references built across the entire franchise. For those who have spent the last year re-watching all the films, studying every frame, quoting every quip, there is a lot of pay off and closure. For casual fans of the franchise who have been empowered by Scarlett Johansson, endeared to Chris Evans, charmed by Robert Downey Jr., or…um…infatuated with Chris Hemsworth, there are plenty of laughs and thrills. It has been an incredible ride, and Endgame is a fantastic finale, but don’t be thrown off if you feel a little grief after saying goodbye to such a history making franchise.
