“The Tank” (** out of four) was an obvious, empty sci/fi thriller that will likely go right into the tank set in 2012 about 6 science workers (Marguerite Moreau, Brad William Henke, Jack Davenport and others) who go aboard a tank on an attempted mission to Mars. Story is told in flashbacks as everyone’s favorite bad guy (Christopher McDonald) is testifying at a congressional hearing about why the mission was a failure. Well-made and well-acted but it’s a lot of noisy running around and arguing over nothing. “Das Boot” remains the all-time classic about war on a submarine or tank and ages better every year.
