Simon’s review published on Letterboxd:
Basically "What if Hardcore Henry, but the camera just does whatever the fuck it wants". How much you enjoy Carter will depend mainly on how much value you place on ambition vs execution. The film is audacious in the extreme, but held back by conspicuous green screen effects and dodgy CGI.
I'd have happily sacrificed some impossible camera movements for more immersive practical effects. but the film is still a thrilling spectacle and a must see for action enthusiasts... just keep your expectations grounded, its flaws are plentiful.
