Ten-year-old Nico receives a threatening letter and now his life is in danger. No one seems to believe him except one person that he doesn't know.
The Warning is a Spanish thriller with an intriguing premise — a boy discovers a pattern of threatening letters across decades, drawing in a reclusive mathematician. The concept blends mystery with mathematical puzzle-solving in a moderately fresh way, but the execution is uneven. Acting is serviceable but lacks depth, particularly in supporting roles. The cinematography is competent without being distinctive. The ending, while attempting a twist, feels somewhat contrived and underdelivered, leaving the puzzle's resolution less satisfying than the buildup promised.
