When they work, submarine movies have a lot going for them: There's inherent drama in a bunch of shouty men stuck in a small metal tube surrounded by an environment that's actively trying to kill them. It's the perfect hotbox for conflicts of loyalty to play out, with no space for easy outs or smoke breaks. When submarine movies don't work, you're still stuck in a small metal tube with a bunch of shouty men for two hours, but you don't get any of that other stuff. Black Sea has the look and feel of a great submarine movie, but a bathtub fart of a script. by Ben Coleman
