While Steve Martin leads with charisma and the film builds in laughs as time goes on, the overall appeal of this movie boils down to if you have a thing for military comedies or have a free block of an hour and half and like Steve Martin. Mitchell's character, Wally, could have amounted to something but even though it begins as his story, his character fades oddly. Aykroyd's character also could have been interesting but his through line flattens and never recovers. Hartman is a worthy opponent but the more he acts the more you aren't scared of what he'll do. As for the titular Bilko, I'm not sure how many lessons he learns and therefore what the movie is really offering the audience beyond gags. The extra half star is for the laughs but comedy must be built on something otherwise the laughs are temporary. The great comedies have undertones and scenes of worth that make you want to watch over and over. I don't think I'll revisit this one, despite my being a member of the Steve Martin fan club.
