There’s a lot to be said about Infinity War that can’t be said without spoiling some of it. Based on the state of my local movie theater on Sunday morning at 10:30, it’s a little hard to swallow that anybody with a serious interest in seeing the movie hasn’t already seen it, but surely these people must exist.

I have thoughts that must be thought about the movie, though, so here’s the obligatory warning: here there be spoilers.

Furthermore, in the interest of not turning this post into a 3000-word monster, I’m going to break it up. Here, then, is the first installment. With extra spoilers.

On Protagonism:

Let’s get one thing clear: the movie is a thrill-ride. It’s hard to look away (and harder still to walk away, for example when your six-year-old in attendance has to go to the bathroom for the third time just when you feel yet another climactic battle looming) for fear you will miss something, and miss something important. The film is eminently watchable.

But from a narrative perspective, I found myself getting frustrated. Every time you start to settle into the groove with one of the bands of heroes (and the fact that there are multiple bands of heroes is maybe the first indicator that trouble is afoot), you have to cut away for an update on the other bands of heroes. There are at least three — and sometimes four — groups of heroes doing different things in different places until the final battle. And this is a Marvel movie, mind you, in full swagger, using every tool they’ve honed over the last ten years — every subgroup is rife with internal conflict between its members, cheeky one-liners, and hilarious deadpan.

In short (too late!), as an audience member, I am fatigued with protagonists. Who am I supposed to root for and identify with? Banner and his performance anxiety? Thor and his abs? Stark and Strange trying to out-Alpha each other? Captain America and his beard? I’ve seen almost all of the movies at this point, and each of these characters is lovable, so I want to root for all of them — but there just isn’t time. Because the cast is huge and the plotlines are tangled and far-reaching, the film is paced like a coked-out cockroach skittering for the sugar bowl. You can’t identify with a protagonist, you barely have time to recognize them in their shiny new duds (seriously, it’s like every superhero gets a costume upgrade in every sequel) before the movie is shuffling you off to the next thing like an overbooked tour guide. Character development? Forget about it. There are no less than a dozen heroes here — it’s enough work just to remember who’s doing what.

Very frustrating.

Until you shift your perspective.

There’s no consistency to be found amongst the heroes. Some are all business while some crack wise, some concoct elaborate schemes and others wing it. The movie even seems to shift in tone based on who you’re following at the moment. No, the consistency comes from the bad guy.

Lurking behind everything that happens is the swollen, ill-proportioned face of Thanos. And once I realized that this movie is pulling a fast one on the audience, I became much more sanguine in my thinking about it.

Thanos is the villain. He’s also the protagonist of the movie.

Thanos hogs the screen time. Thanos has all the character development. Thanos chews on the scenery for every shot he’s in, and thanks to the magic plot devices, he’s literally hiding around every corner. Thanos, in other words, takes the hero’s journey in this movie. Every twist and turn that happens in the movie is centered not on the Avengers — a kicked anthill is as frantic and as useful as they seem to be in the movie —  but on Thanos.

He hears a call to action when his home world is plunged into strife, and goes on a quest to deliver the same peace to the entire universe (just, you know, not in the way we’d prefer). He meets a mentor character who helps him in his goal (Red Skull, we hardly knew ye!) He and his band of villains have all the try/fail cycles. (Didn’t get the time stone there, didn’t get it there — third time’s the charm.) He has to make sacrifices to meet his goal. And the final victory brings him within an inch of his life.

Thanos is the protagonist of Infinity War. And the filmmakers know this: in the closing credits, where we usually get the grim but reassuring message “The Avengers will return,” we get instead “Thanos will return”. That’s not just a cheeky jab to drive home the stake in the hearts of all the Loki fanboys (and fangirls. And the fanboys/girls of Spiderman. And Groot. And Black Panther. And and and YOU GET THE POINT). It’s an acknowledgement that this movie is not about what — or who — you thought it was.

Once you’re down with that, the movie becomes a lot easier to digest, narratively speaking. The quest we’re on is Thanos’s, and the Avengers — legion as they may be — are but speedbumps on the residential suburban street leading to the eradication of half the population of the universe. Our favorites are cannon fodder — occasionally seriously inconveniencing the real protagonist, but ultimately never really standing a chance. Which is the posture of all the villains in every other Marvel movie to date.

I’ll point out that this trick of the light only works because the filmmakers have pulled the cinematic bait-and-switch of turning the Infinity War story into two movies. When Thanos receives his comeuppance, as he must in the next chapter, Thanos’s current arc, which is riding the hero’s trajectory, will come crashing back down to reality.

But once you engage with the movie on its own terms (and failure to meet a story on its own terms is basically the biggest source of strife, not just in Marvel movies, but in any cinematic universe — I’m looking at you, butthurt Star Wars fans), it starts to make a lot more sense.
