Greyhound
I wasn't expecting anything from it, but it was a treat. There's pretty much no extraneous exposition, just a straightforward story of a group of destroyers (American, British, Canadian, and Polish) protecting a convoy crossing the Atlantic. They let the atmosphere tell the story for a lot of it with almost everything said directly related to what's going on. There's only one minor detour from the story that's kinda out of place, and a scene or two goes on too long, but the overall movie isn't hurt by the few hiccups. The only real downside is you need an Apple TV+ subscription to watch it.
