The Shallows ★★★★

Watching the mediocrity of Adrift made me remember how much I love this movie. It's so tight. Gives you the exact amount of back story you need in first few minutes; nothing more, nothing less. Then it just lets the tense story and the commanding performance by Blake Lively do the rest. This movie really does ring every ounce of suspense out of what may seem to be a ridiculous setup.
