Felipe Fritz’s review published on Letterboxd:
This movie has many flaws, but boy does it know how to make up for them.
It knows the value of fanservice. Not the kind that feels cheap and forced, but the one that rewards long time viewers wih moments like T'Challa calling Clint by his name after saying he didn't care in Civil War or Nebula winning at paper football after never having won at anything in her life.
Not that there's no big fanservice (the entire final battle is one awesome fanservice moment), but those small moments are the ones that make me really get a smile on my face.
My favorite scene is the funeral scene. As epic as it is to watch every hero coming out of the portals, seeing them all paying their respects to the man that started it all while Alan Silvestri's beautiful score plays will always beat it for me.
It's not a perfect movie by any means (it's probably the Russon's weakest MCU film), but it's the perfect movie for what it was trying to accomplish. To reward those who have been with this movies since the beginning by giving them the action, the characters, the fanservice, the emotion, and the closure they deserved.
