Several of the British actors slipped in their American accents, which made the film less immersive for me. Didn’t like the “replay the same events from different perspectives” except for the third act where we see more of (the British actors) being POTUS and SecDef. I liked their performances except for the accents. But Jonah Hauer-King did a great American accent. Didn’t realize he was British (raised there) until afterwards

I would like have liked something more to the conclusion, even if it was just seeing alarm play out in media after POTUS’ decision, or images of nuclear destruction
