Not only is "I Love Lucy" arguably the greatest American sitcom in TV history, it is arguably the greatest American series (sitcom or otherwise) in TV history. So I was very glad I got the chance to watch it, and learn new things about Lucille Ball, Desi Arnaz, and "I Love Lucy." I guess the only people who seem to dislike this documentary are super-fans who supposedly learned nothing new or interesting in this documentary. This reminded me of the same criticisms that "McCartney: 3, 2, 1" received from super-fans, who didn't like that one because they didn't learn anything new. Well, I'm fans of both Lucille Ball and Paul McCartney, and I learned new things about both. But I'm not a super-fan of either, so I guess if you are, "Lucy and Desi" may not be for you. But for everyone else who knows about Lucille Ball and "I Love Lucy," this documentary should not be missed.
