This film features Keanu Reeves as John Wick, a man consumed by sorrow who spirals into violence after criminals harm his dog. A wave of destruction follows. Audiences generally respond favorably to revenge stories, and there have been many successful examples in recent years. After establishing the premise – Wick’s mourning, finding solace in an animal, then experiencing that loss – the movie transforms into a relentlessly entertaining action film. Reeves portrays Wick with a brooding intensity and imposing physicality (though his facial hair is peculiar), dominating every scene. He methodically eliminates those who wronged him. Essentially, that's the whole story! The characters aren’t particularly developed; it’s undeniably absurd, but it’s also immensely enjoyable. It’s an action movie designed for success, without trying to be anything more. A solid 7/10
