I will watch documentaries on practically anything, even subjects I'd otherwise have no contact with. Menudo is a great case in point; it's not my style of music whatsoever, but the series interested me a lot. I see complaints of over-long documentary series by posters here all the time, but this felt well paced to me. For a band that had a concept of replaceable parts with its members, the director did a really good job of making every member who appeared on camera feel as distinct individuals. The purpose of the series was to shine a light on the exploitative manager of the band's management (and it does a very good job of that), but I would have liked a little more information about the band itself in places (there is almost no information about the songs themselves. Did any of them reach the Top 40? Did each iteration of the band perform the same songs or did they keep making new music?).
