Has potential.
A nicely contained, one-location, thrill ride.
The director has already done a great job with a very contained film. The Autopsy of Jane Doe (2016). Another contained film that excelled is 10 Cloverfield Land (2016).
Historically Hitchcock did a great job with several films such as Lifeboat, Rope and Rear Window.
So whilst it may sound a bit too contained, small and merely a tiny portion of a bigger story getting stretched out, I wouldn't give up hope. These sorts of films can deliver. Dracula running amok on a ship has potential.
