“Osomatsu-san” (“Mr. Osomatsu”) is a throwback show, something I have not readily encountered. The show originally ran from 1966 to 1967, in what would have constituted the First Wave of anime (and could have been shown on US television, when I had my initial encounter with anime back in 1964). It was everything you might recall from that time: flat or non-existent backgrounds, overly–broad characters, simple art design and pointless plots.
