Dull start, and then it gets better

Rating: 7/10 (21 May 2019)

Hard to understand why we got 15 minutes of a very ordinary romance, before we got to the substance of a ship in peril.
If it needed to be included at all, it could have been done as a flashback, after we know that the man's life is at risk.
Till almost the end, one can not be sure who will live, or if anyone will survive.
Once it gets going it is rather good, showing real-life perils.
