I gave this crime series a 6. I would have given a 7 if the acting of nearly ALL actors would have been better. The city location of each episode is quite decent and perhaps even tempting for future vacation destinations. All of the ship's locations (eg, auditorium, bar, restaurant, rooms) are an unnecessary distraction. Actually, who would like to book a cruise on a ship that is constantly involved in murders??? The 1970s Love Boat series was - at the very least - appealing to consider a cruise. This series enables the very opposite thinking. That very thought warrants an overall 6 rating. The plots are, however, too decent to warrant the overall 5.4 average rating.
