Started well but far too many plot holes and McGuffins used to bring the story to a conclusion. The final episode just fell apart in the edit or scripting. Somehow characters teleporting from Glasgow to Edinburgh, murder interviews happening on a park bench, Suranne Jones not being found in a torpedo tube directly after the XO saying he wanted the suit and would retrieve it, her screaming and banging not being heard by the sonar officer but tapping a torch was, a compartmentalised submarine sinking to the bottom until someone remembered to pulled back on the steering wheel, 3/4 of the crew disappearing from the boat, the UK Navy base not having a location for Vigil but having a nice green dot on their screen for the location of an American sub which previously they didn't know was secretly tailing Vigil, Surrane Jones going unconscious presumable due to carbon dioxide poisoning but then instantly recovering and being able to run through a bleach filled giant warehouse part of the submarine lit in red for no reason, the main baddie having absolutely no scripted motivation whatever. Just really really poor.
