If you loved The Marine, try The Shallows
A bridge between a film you've already seen and one most people haven't. Here's what they share, and what the second one does that the first one doesn't.
What The Shallows is
Secluded beach. Summer wind, distant buoy bell. A surfer ignores a grim local omen. Soon circling, she's bitten, bleeding, and stranded on a buoy offshore. A predator waits. Classic creature-feature setup, elevated.
