"Glass Onion" falls short of its ambitious potential. The convoluted plot and disjointed storytelling create a frustrating and confusing experience, leaving viewers scratching their heads rather than immersed in its supposed mystery. The attempt to blend multiple genres feels clumsy and haphazard, like witnessing several chaotic films collide. Lackluster performances and an unreliable narrator trope add to the disappointment, leading to a disheartening conclusion. With a lack of coherence, poor pacing, and underdeveloped characters, "Glass Onion" fails to deliver on its promise of a thought-provoking experience. It's a missed opportunity in cerebral cinema, and unless you enjoy convoluted narratives, approach with tempered expectations.
