Arun George’s review published on Letterboxd:
The film is the very definition of "mid" in every single department, and that even includes Anthony Mackie's 0.5 smile while mouthing each line. There's a lack of a clear antagonist, there's an attempt at building a blended sequel to both The Incredible Hulk (a film that was almost forgotten from the MCU) as well as The Falcon and the Winter Soldier, but what hurts the most is how directionless the whole thing feels. The writing shows some signs of life in the second act before fizzling out completely in the final act.
Plus, not bringing back Edward Norton's Hulk even for a brief cameo was a downright bummer (..and no, I did not want Mark Ruffalo's Smart Hulk in this), especially when you have Red Hulk at the other end of things. Harrison Ford's version of President Ross also feels rather half-baked; I think some of the blame should be attributed to the poor dialogues overall. Kevin Feige, with Avengers: Doomsday just a little over a year away, it feels like you've got a lot of work to do to restore the MCU's lost glory.
