I’ll admit up front that this is a tautly constructed suspense tale, even when some of it is obvious. However, as a diver myself, I really cringed through a lot of the opening and cavalier stupidity of the choices Mandy Moore (This is Us) and Clare Holt (The Originals). It wasn’t unrealistic…people really are that dumb, especially when trying to prove something to themselves; it was just painful.
Matthew Modine (The Hippopotamus, Stranger Things) was a surprisingly well done character too. His motivations and choices managed to avoid the expected at almost every turn. For a small role, his was an important one to keep the movie on track.
Co-writer and director Johannes Roberts’s crafted a good horror film out of a fairly simple concept that plays homage to Jaws, Alien, and dozens of other similar efforts but without feeling like a copy. The camera work and production also did a great job capturing the action and underwater world. I can see why it was such a surprise hit. I can’t say I’d need to see it again, but Roberts clearly has ability and a sense of how to hold an audience. I’d be curious to see what he manages next and if he can apply it to something a bit less cheap-genre.
