Keatonphiles consider Buster's stint at Columbia in the late 1930s and early 1940s to be the nadir of his career. The MGM talkies were awful and not right for his style, but some of them were watchable and all had good production values and supporting players. The Educational shorts, made while Keaton was depressed and drinking almost constantly, are much better than their reputation, even managing to be creative and funny even if they don't approach the greatness of Keaton's independent work. But Columbia? The home of the Three Stooges? Not a fit for Keaton at all, especially when he was given awful material and paired with Elsie Ames, the human embodiment of shrillness itself, ugh.
Mooching Through Georgia (1939) is surprisingly good for a Keaton Columbia short. Buster is kind of a dope, but he is allowed clever and resourceful moments a midst the uninspired slapstick and silly accents. The Civil War setting might make you pine for The General (1926), but it's pretty good nevertheless. Not a gem, but overall painless.
