Cats (2019)

Cats (2019) stands as the worst CGI in cinema history, with its "digital fur technology" creating humanoid felines so disturbing that Universal rushed a patched version to theaters after opening weekend—a move that saved only 5% of the box office free fall. The uncanny valley nightmares of Judi Dench, whose fur coat fused grotesquely to her skin, epitomize the decade's most catastrophic effects. This debacle outperforms #2 by making even major studios panic-patch, whereas lesser flops merely endure ridicule. Over 70% of audience surveys cited the CGI as the primary reason for the film's $113 million loss, cementing its infamy as the benchmark for rushed digital horrors.
