Boom in the Moon (1946) has quite the reputation, many claiming it to be the nadir of Buster Keaton's career. It's hard to argue against that claim. It's not only unfunny ninety percent of the time, but it's boring and staid in every department. Keaton sleepwalks through the lengthy dialogue scenes, likely because he did not speak Spanish. He reuses gags from his older films, but as creative as they are, they only work in the context of better, more coherent works than Boom in the Moon. Even Columbia and MGM at its worst gave the master more to work with.
Really not worth the time of anyone who isn't a Keaton completionist and even then, you might want to skip out.
