Hard to understand how this went so wrong. Almost every single development feels like out of all the options available to the momentum of the story, whichever is the worst possible choice is the one that Mary goes with. Over and over and over. I mean you've got Acadamy Award Winning Gary Oldman literally on deck here, in what on paper is actually a very cool premise. I even have a predisposed fondness for boat movies. How was this not even "just okay"?
Final rating:★½: - Boring/disappointing. Avoid where possible.
