Netflix just dropped its movie adaptation of Ruth Ware’s novel, and honestly it’s so good it deserved a theatrical release. Before you hit play, I recommend putting your phone away and dimming the lights (I use a blue light bulb for the perfect moody glow).

The film stars Keira Knightley, Gugu Mbatha-Raw, and Hannah Waddingham, along with a cast of British actors so authentic you might want subtitles to catch every line. Set aboard a luxurious yacht filled with the ultra-wealthy and well-connected, the story follows journalist Keira Knightley as she witnesses a passenger fall overboard. When no one believes her, she risks everything to uncover the truth.

In this murder mystery, everyone’s a suspect and possibly a villain. Not sure when was the last time I saw a movie with this much atmosphere and mystery. It’s suspenseful, exciting, and well produced. At just an hour and a half, it’s a tight thriller that keeps you guessing until the end. If you love a good whodunit, this one’s a must-watch.
