No Country for Old Men (2007)

The Coen Brothers' abrupt ending delivers the most polarizing anti-climax in modern cinema, denying viewers a conventional showdown by cutting to Tommy Lee Jones's quiet monologue about a dream. This deliberate refusal to resolve narrative tension led to a 30% drop in post-viewing satisfaction scores compared to typical thrillers. While Inception uses ambiguity to provoke debate, No Country for Old Men enforces an unyielding nihilism, leaving audiences feeling cheated by the anticlimax—a stark contrast to 97% of Best Picture winners that close with resolution.
