It is a best to go into this movie with at least two things: 1) no expectations and 2) a working knowledge of comic book lore. Given everything that has happened in the MCU movies, would this movie be the coda we all needed? Yes and no.
SPOILERS AHEAD: The first 45 minutes of the movie is bogged down by the survivors of The Snap coming to terms with what Thanos did at the end of Infinity War. This stands to reason though it goes on a too long, a sharp departure from Infinity War’s quick pace. (For those of you familiar with Kill Bill Vol. 1 and Vol. 2, you may understand the kind of contrast I’m talking about.) Given the overall scope of what the MCU movies were ultimately trying to accomplish, this emotional ride is necessary and therefore forgivable. It’s hardly the worst part of the movie.
The entire middle of the movie is a muddied mess involving time travel which goes off the rails the more it involves the major characters’ pasts. (You’ll also be sorry if you forget the timelines of everyone’s pasts, otherwise the plot is going to leave you in the dark.) The Avengers travel to the past in an attempt to gather the stones before Thanos does which was probably the worst thing they could have done given Thanos’ intelligence.
Once they do acquire the stones, though, the movie finally gives us the action we’ve been aching for the entire movie. Thanos attacks Avenger’s HQ with our mercy, leading to the absolutely fantastic opening confrontation between, Cap, Iron Man, and Thor. (My favorite moment of the entire movie? When Captain America picks up Thor’s hammer as they battle Thanos. Damn, what a moment. My second favorite was the shot of Tony and Pepper fighting side by side.) As it goes on, the battle swells entirely too much, involving everyone you can possibly imaging since the first Iron Man movie. Even given a running time of three hours, even this amount of time doesn’t seem enough to do the final battle justice to everyone involved. Especially troubling is the lack of any punch out between the Hulk and Thanos, as the Hulk has been reduced to a joke for the entire movie and never gets a rematch from Infinity War. I think it would have been more appropriate of the script to reduce the battle to a few participants and have them outwit Thanos seeing how none of the heroes alone are a match for The Mad Titan. Instead they beat Thanos in a most unexpected way, unexpected because we all should have seen it coming at that moment. (But when it happens, we’re given a really great line.)
The movie doesn’t end there because now we have to deal with the cost of having defeated Thanos and wrapping up some of the major players’ histories. The movies mostly succeeds here, especially on Cap’s behalf, while Iron Man and Black Widow are grieved for. The completion of Thor’s story arch ultimately remains to be seen, strangely enough…
The movie worked on several accounts; following through on the most important Avengers’ histories, utilizing the MCU movies trademark humor, and all the Easter eggs only die hard fans of Marvel comics would understand. On the other hand, no pun intended, the script is not nearly as tight as Infinity War and gives us hardly any action until the climax. There are also some rather large plot holes. (Um, Thor’s two hammers for starters.) Does this mean that Endgame is that satisfying coda I asked about earlier? Sort of, but it could have been so much better. All things considered, Avengers: Endgame gets three and a half infinity stones out of six from this fanboy. Excelsior!
Oh, and for Pete’s sake, pee before the movie starts.
