a submarine lose in ww2 re appear in 1981 and david jason character hardy ( the only survivor of it last voyage ) be ask to go back with a crew and retrace the step of the submarine last journey ( why . you may ask . well obviously it wouldn not be much of a drama if they just find it and put it in a maritime museum representp ) anyway after the recent hype about the drama i do have high expectation but be disappoint . there be lot of submarine jargon which go over my head and so unless you have a particular history with or an interest in submarine and then i be assume most people would have the same problem . and so it get a little confusing . i wouldn not attack the plot too much because after all it be call ghostboat and so you expect it to be a little far fetch or supernatural so that fine but . at the end when the navy and the russian navy ( or whatever theyre call in russia ) close the case on the strange going on and there be no mention of and never any mention of and all the other boat they blow up along the way . and a for the hostile german aircraft . well i can only assume that they be imagine . now i know there be some grey area a to which be go on in the past and which be in the present but hardy do state that it be only 1943 inside of the sub and still very much 1981 outside . hence the reason why the russian of 1981 be get a little anxious at the sight of the sub on it radar . so i be assume that the boat they blow up be real and of 1981 too . but . if i do get too confuse by all the submarine jargon . and completely miss something due to this fact . and anyone know any different . please tell me . thanks represent ) .
