Hell and high water are a setup for genre adventure that Black Sea only partially delivers. But in Hollywood's slack season, we'll take what we can get. Greed makes a great plot catalyst. And director Kevin Macdonald (The Last King of Scotland ) uses Dennis Kelly's script to shoehorn The Treasure of the Sierra Madre into a submarine.
Excellent submarine thrillers like Black Sea get much of their visceral oomph from making it seem as if the camera operator - standing in for us - is just as constrained as the characters.
