The quality of a film shouldn't be based on its box office numbers alone, but the analysis of these earnings is (usually) a good way to understand what global audiences are most interested in seeing on the big screen. Over time, countless great, highly praised movies like Blade Runner 2049 and Children of Men have become box office bombs. On the other side of the spectrum, films that are poorly reviewed by critics and, at times, general audiences, have managed to obtain a wild amount of earnings.
