I fully bought into this and it has jumped into my favorites of 2019. I don't know what's there to complain about... the videogame cut-scene aspect of it all? It's deliberate and it's joined by some great acting (the Macaulay Culkin look-alike was wonderful), aside from being one great sweeping narrative. It was tense as fuck, Duke, even if we all knew they were getting out of the mine shaft. The letter surviving the cascade was a bit of a stretch and about the only time I was taken out of the moment by lack of proper suspension of disbelief.
I liked the reversal that we're made to expect Colonel Mackenzie as a soulless hard-ass and he's a reasonable man fighting the same war as everybody else.
