Reasonably engaging disaster movie suffers from TV movie values and a pretty dopey script. Heston is remarkably restrained (probably because he's been through this so many times already), but Cox goes unhinged faster than a caretaker at the Overlook, which strains credibility (or aren't submariners trained for high stress situations?) The domestic side with the submariners' wives is also turgid and adds to the TV movie atmosphere, but seems a prerequisite for this sort of film.
