The idea might pass muster, if you like the idea of a haunted submarine that wants to start World War III for no apparent reason, but the execution is terrible. Nothing much happens for long stretches, apart from sweaty submariners looking at dials and twisting valves while muttering naval mumbo-jumbo with a stiff upper lip. At each plot point the story becomes more ludicrous, and even the actors seem not to have the heart for it.
I should have known early on when nobody knows the boat is in need of exorcism and the dock workers can't open the hatch whatever they do. A naval officer then has a go, apparently because he's a toff and obviously knows more about opening hatches than mere manual workers. He seems more surprised at his failure than when a few seconds later it opens all on its own, and nobody bats an eyelid. I should have switched off then, but I got to the end (just).
