Darren Carver-Balsiger’s review published on Letterboxd:
This is a year of average Marvel movies, with none standing out in terms of quality (in either a good or bad way). Spider-Man: Far From Home is the most average of them all, not even reaching the highlights of Avengers: Endgame or the lowest points of Captain Marvel.
Spider-Man: Far From Home works as a superhero film, if that's all you're interested in. It has likeable characters and decent action sequences. Compared to Endgame it is fun and simple. Far From Home is also a really funny movie, which makes for easy viewing. The writing is clunky and forced, worst exemplified by an abrupt opening sequence and a later scene where the villain lays out his motives to his colleagues who should already know. By contrast, the film's greatest sequences are trippy illusion-centric action scenes that stand out from everything else.
Whilst Far From Home has some good inner conflict for Peter Parker to struggle with, it shows a great limitation of the MCU. Spider-Man in these films is defined by his position within the MCU, not who he is as a character. He will never be in a small movie again, as his films feel mandated to connect to the wider cinematic universe in at least five different ways. It's not necessarily bad to have a cinematic universe, but Spider-Man can no longer be that relatable kid any more, or be in a story that stands by itself and comments on problems mere mortals have to face. "Bitch please, you've been to space," says Nick Fury, and with that I think I have to accept that something as profound as Spider-Man 2 will never happen again when these films can no longer totally be detached from any other.
Spider-Man: Far From Home is as enjoyable as most films in the MCU and works very well as a superhero blockbuster. It never really gets anything wrong. That said, it never becomes as fun as Homecoming or as powerful as Raimi's films. Solid stuff overall, but unexceptional.
Side-note 1: Anonymity basically doesn't exist in the MCU but it's interesting to see it preserved in the Spider-Man films.
Side-note 2: Those end credits scenes change everything and have me very curious for the future of the franchise.
Side-note 3: ***SPOILERS*** J.K. Simmons' cameo is amazing and steals the movie. The best casting decision in the MCU was to bring him back.
