While the show is not a masterpiece, it fulfills its purpose gracefully and the cast is what it should, we are not going for an prize here but even Irene, not so experienced as the other actors, does it's role as a real Madrid posh girl, insecure and that thinks everything will be easy.
The boys feel like real suburb dangerous ones and J. Coronado and the rest of the cast do a good job having in mind that is a TV show with a limited budget.
If compared with similar shows, the way each episode end with a cliffhanger is simply impressive and as I see, hate actors is without doubt not positive at all and even dislike the show is an opinion to be respected, is not fair to blame on one actor or actress.
