One of the most influential movie critics of all time, Roger Ebert was never one to prioritize niceties when it came to writing poor performance reviews. His opinion held the weight of an audience member in every punctuation mark, swaying them to see or not to see a film, including curating a list of the movies he considered to be the greatest of all time. When it came to assessing the worst movies he had the displeasure of watching, Ebert held no punches when awarding 0-star reviews to some of the worst comedies of all time. Comedy is subjective, but his opinions on those features at the bottom of the barrel (and the ones he deemed below that) are scathing and unforgiving.
Often leading the critical opinion charge, there were moments in which Ebert went against the grain in his reviews; however, that is not the case for these films.
Disclaimer: If you like any of these films, that's fine. It's just ONE film critic's opinion.
