A lot of people in these reviews don't seem to understand that this show is for Argentinian Disney Channel, hence why the show and songs are all in Spanish. If you don't like that, instead of leaving a bad review go find one the many shows produced in English on Disney or Netflix or anywhere. It's also a telenovela which is why it has that melodramatic over the top style, that's not automatically a bad acting thing or cheap production thing.
Compared to the shows produced for Disney US or Disney UK it's certainly not any worse. Yes the show drags out too much, each season has 80 full hour episodes and would have been better to have either shorter episodes or less episodes. However the plot is interesting and show is enjoyable. I watch in Spanish with English subtitles as I don't speak Spanish and still find it enjoyable to watch (however I'm also part deaf so subtitles are permanently on, I understand why some people dislike subtitles)
The show is ridiculous at times, Tino and Cato seem to only exist to be like court jesters which at times is annoying, I just fast forward most of their scenes. Also they could have written a larger range of songs, they largely sing the same 5 or so songs on repeat the whole of season 1 even though they have a regular open mic style contest. I've watched other shows from Argentina in a similar style and they manage to produce a full album each season and they have far less episodes to do it over.
