"Tini" has quite a bit more mature themes than "Violetta".
Nevertheless, it is still very suitable and quite easy to understand for younger audiences as well.
Firstly, the outfits, cinematography etc. Are absolutely stunning, especially concerning the grand concert.
What amazed me most besides that was the way Violetta found herself by finding a piece of her past, by learning where her mother originated from.
Her revolution is breath-taking in a way.
Also, the way León and Violetta find their way back to each other again is just beautiful, in a dramatic, hurtful way. However, the rumors of his affair with a co-star that sets everything in motion are really very cliché. Furthermore, Léon at first staying oblivious concerning this makes him look really stupid which is just sad.
