Wesley R. Ball’s review published on Letterboxd:
The cinematic equivalent of the Facebook like button. Safe, inoffensive, standard fare that doesn't really go as far as it could have; but is doubtlessly fun along the way. It's not breaking any barriers or revolutionizing anything for anyone, and if you've seen any of the earlier MCU movies, you've probably seen this one already. I would have changed or completely cut out the first fifteen minutes or so- some of the downright worst editing choices I've ever seen that just all collides together in a jumbled, indecipherable mess. It's nothing more or less than it should be, though- an adequate introduction to what I can only assume will be Endgame's Deus ex machina, or at least part of it anyway.
