There are many plots in the series. One is the relationship between the protagonist Edgardo Diaz, and his mother, who do manages the boy band he creates. Then we have the plot between Edgardo and the choreographer and costume maker Joselo Vega, who is a role model for the group, and a friend/advisor to Edgardo. Then we have two Menudo fans who never grow old despite the years going by, Renata and her best friend. Then we have the plot involving Renata's daughter, who in the present interviews an aged Edgardo. So among all those stories, there is very little coverage of the band members themselves, and what happened to them after leaving the band.
How does it feel to be ex-famous? That would be interesting. And how did they created the lyrics, songs that became so popular? Joselo himself, we never see him creating the dance moves. There is very little about the romantic live of members.
In short, the series are fun, but with too many subplots and unnecessary characters.
