I liked it. That's the thing. I just liked it.

Rating: 7/10 (27 April 2019)

First two hours were a very, very slow build. I know a great ending needs a compelling build but this was too much and too boring. Last hour was fun, but too Disney, and not enough time for us to enjoy the characters that have been so carefully crafted for us over the years.
"Endgame" was a not-entirely-successful attempt to leverage the same emotion and desperation of "Days of Future Past." Think about how you felt for the few mutants left in the world staving off the relentless onslaught of Sentinels in DOFP and compare that to the saccharinely-sweet Disney approach to "Endgame". "Hey, lets try time travel?!"
In the last hour think about how each star in the end of "Endgame" predictably got their little slots to say or do something.
That's Disney.
In contrast, the opening battle with Thanos in "Endgame" was emotional and severe. Captain Marvel puts Thanos in a headlock. Thor chops his hand off. Awesome! The scene was perfectly crafted. Super quick. The whole movie couldn't be a fight scene but "Endgame" lost the classic Marvel flair RIGHT after Thor ended Thanos.
Great cameo by Jim Starlin - creator of Thanos - as the group therapy leader (I think that was him.) Nice touch in the mighty Marvel manner
Too much screen time for the uber-uninteresting Nebula (who I do not remember from the comics.) More time for her than favs Black Panther, Dr. Strange, Drax, Spidey... Drax was CREATED to kill Thanos. "Drax the Destroyer." I digress.
As usual Robert Downey Junior was fun to listen to and the "glue" IMO for the movie (not Chris Evans)
Thor's "thoughtlessly funny" jabs at others (Rocket Raccoon as a rabbit, etc) have been funny throughout the series but he was not a Thunder God in "Endgame" and his humor in particular - both as the quitter and as reinvigorated Avenger - took away from the story. Complete momentum killers.
Too many contrived Disney moments like the unlikely female Avengers team up in the middle of a planetary war; jokes and yucks in the middle of said war, and Pepper, inexplicably, in a metal suit.
Hulk doesn't fight (at all) in this movie and therefore doesn't get Thanos back for the beating he took in the beginning of "Infinity Wars." That. Was. A. Complete. Opportunity. Missed. Someone overthought something in the brainstorming session
Cap lifting the hammer. I know it's a nod to Cap being "the first Avenger" but the hammer is supposed to be sacred. In contrast, Vision's hammer moment in "Age of Ultron" was clever and classic.
Speaking of Vision, it sucks that we never really got to see him "show his stuff," like earth-pressing maximum weight + density and Wonder-Man-level super strength
I'm an old school Marvel fan. I enjoy every movie (even the awful FF and X-Men failures) because as a kid I always wondered what it would be like to see these amazing characters and stories on the big screen. After the buildup arranged by so many Marvel movies I was psyched for "Endgame." I expected more. I wanted to love it. I liked it.
("Spider Man Homecoming" remains my fav Marvel movie)
