The first chapter shows an unrealistic view of the montaners, the show belongs to a different era of the early 2010s when the family was still somewhat a mistery. It has really poor acting, the settings and interviews only make it worse, with many contradicting views of the world, this show isn't really worth a second look, much less it being a show (Mr Montaner should have written a book or have done an interview instead).
Not sure why the plot surrounding the "family" is being pushed as research shows the "juniors" have been attempting to make a crack to the music industry for more than a decade with little to show for, I have to note the great charisma of Mr. Montaner, despite not being able to act, the quality and caliber of his power of conviction and abilities to navigate and manage his family is undeniable, unfortunately the rest of the cast cannot say the same about his personal charisma with the exception of some moments of those added to the family.
There has been a lot of speculation regarding the family and its "cult-like" nature, after seeing this show, one can't deny there must be a grain of truth within the statement.
