If you watch 15 minutes, it looks like a brilliant film that you're walking in on too late, but that might have made sense with the full context of the production. But it is not this film. The more I watched, the more I became convinced my Netflix had accidentally shifted into another film.
Much of the plot appears to have been culled from the 2002 Ghost Ship (which is a great watch), stitched together with a ghostly Titanic and a mishmash of Hitchcock and Kubrick references. The Rod Serling voice over announced, but did not create, an ending.
There is no resolution because there is no plot. Perhaps it is this sensation of directionlessness, nonsense, and heavy-handed reference to other films of the genre, that makes this movie truly horrifying.
