it be easy for a movie that try to be suspenseful to wind up be merely uninteresting . it happen quite often . not only be dark harbor uninteresting and but it be very poorly do . scene after scene be tack on to an otherwise overdone premise . a troubled couple pick up a troubled stranger only to find more trouble . some movie build tension by build the story . dark harbor keep add on to it story but never building upon it . i be hop that like other movie and the suspense would finally explode . it never do . also and the character have no continuity from scene to scene . they may act one way in one scene and but then act a completely different way in another scene . at first and you think that they be merely out of character and but by the end you realize that they be not really character at all . they be just prop for the final twist . the final ten minute try to be shock . instead and it rather lame and uninteresting . the only thing that be shock to me be that the movie finally end . at less than ninety minute the movie still feels way too long . this isn not one of those low budget gem . it more like a counterfeit watch that break as soon a you take it home .
