I felt like I read a ship watch journal log. Little is known about except that the captain was single, devout, missed all the meals while sailing in the gap, and he did a good job for his first crossing commanding a screen force.
It’s not about greyhound the ship, it’s about the captain only. You don’t see life onboard as most shot was in the bridge and CIC. you don’t see other ship or the enemy’s bridge. It’s about the burden of command.
Action scene and CGI were superb.
If you ever served in any navy, it’s a must to watch.
