I'd bet that if a commensurate TV series like Merli (Merlin) was in a more familiar European language or an American TV series, it would be a huge hit. It is in Catalan, a language spoken by about 10,000,000 people, most in Barcelona and its surrounding area. The concept is ingenious, but there are lots of ingenious concepts. What makes this a great show is that the realization of the concept is wonderful. Don't take my word for it. The series has already been optioned in the U.S., France, and other countries. A non-conforming high school philosophy teacher (philosophy in high school?) brings classroom learning to life, but also becomes a central agent of change in the lives of his students, their parents, and the other teachers. Life changing is not always positive. Merli is not a do-gooder. He is clever, deceptive, even desperate at times, but he knows who he is, and knows how the world works. The entire cast is terrific. The scripts are so smoothly written that the actors seems to just ease into the action. There is rarely a wrong note in the series. It's nothing like American TV shows about high school students that portray them as brats or goof balls or stereotypes. It's available with English subtitles. If you know a Romance language, you will probably catch some of the dialogue. Catalan seems a mix of Spanish, French and Italian. I am waiting for season two to be available. I binge watched the first season in four days.
