Greyhound is watchable but a very mediocre WWII action movie. With no character development and so-so action sequences, Greyhound doesn’t have much to offer. It feels like a TV movie made to watch on rainy Sunday when you don’t have anything better to do.
The last movie from Christopher Nolan (Memento, TDK trilogy, Inception, Prestige, Interstellar) received excellent reviews, some of them calling it maybe the best war movie ever. Well in my humble opinion it is one of the most disappointing movies of 2017.
