Matt Kraus’s review published on Letterboxd:
Basically a really engaging two-hour guitar solo by Roger Deakins, with George MacKay holding things down incredibly well in the lead role. Lots of incredible moments on a surface level, and I was pretty much into it the entire time. Emotionally? I couldn't have cared much less, and this feels less like a bleak war movie than an "exciting" adventure movie. That's certainly not a crime, but the idea of this potentially winning Best Director and Best Picture just two years after "Dunkirk" was RIGHT THERE irks me.
Anyway, this is just a really well-executed thing by everyone involved. I wouldn't be angry if I watched it again. I also don't feel like I need to.
