Mission Impossible: Fallout
Watched it again the other day. Forgot what a genuinely great movie this is. Cruise is flawless, Cavill is a great addition too. The stunts, theme music, locations......just all first class. It also doesn't have that almost 'silly' edge to it that some of the others did.
Greyhound
It was good, but not a lot really happened. You seem to join a convoy in the Atlantic and see how they get on, and can't even remember if you see them make it across. It just sort of ends when they are out of danger.
It's worth a watch I would say but it's far from the most memorable war movie ever. It did give quite an appreciation of what people on the boats went through trying to avoid the hidden killers that are the submarines.
