Anyone who’s ever hummed, ‘Sunny day…’ will get a kick out of this winning doc, which spans the history of the PBS stalwart. Long-forgotten segments and characters will leap back into your mind, as you learn about the evolution of the show. Not only is it a tremendously fun trip down memory lane (including modern-day interviews with everyone from the creators to the original cast), it’s also a revealing and touching history of one of television’s most important shows.
4/5 stars
