This is a 20's something show about life, school, sex, and relationships. While purported to be freshmen, it is clear that many of the 1st year students are likely in their early 20s, some still living at home, others near campus.
The dynamics is centered around love, life, and arousal of a group of philosophy majors. The premise makes for an interesting and broad story as attitudes adjust through the awareness of what they learn. In this youth oriented era, sexuality is loosely defined, breaking down strict barriers between gay and straight. While their are some characters are fall definitely into these roles, the main cast finds the convenience of sex with whomever is closer at the moment of passion, regardless of gender.
The adults play a smaller yet significant role as they deal with the realities of life. As with all people, sometimes the responses are mature and at other times impulsive or conform to long held beliefs. To that end, seeing them as imperfect creates authenticity.
As an American, I do enjoy the European view of Trump, guns, and violence. We so often look at other nations as being dangerous, wreak less, and cesspool of crime, yet ignore the very same, if not larger issues here at home. It is good to look at ourselves through the eyes of others. There is much to learn from the few lines of dialog that addresses Spain's view of the US.
It is interesting that while American TV has all but abolished smoking; as there are proven studies that it has a direct influence on use and acceptance, in Europe it capture as part of the realism of society. I won't deny that I would prefer a smoke-free environment but I am mindful that I am guest invited to watch a show produced outside of my sterile world.
My only complaint with the show is a relatively small scene in the 5th episode. As one of the characters walks through a gay bar, it is seedy, dim, sex is occurring against every bare wall, and drug use is rampant. For a show that tears down stereotypes and provides a refreshing view of human sexuality, that scene fell upon every trope about gay people and what many conservatives believe happens. It was an insult to the LGBT community and I hope the showrunners learn from the error of their ways.
Sans the stumble in episode 5, it is a compelling drama of young people finding their way in life. The fact that many struggle financially also brings greater realism to the characters...a point often missed in US shows. A solid show with much to offer those willing to open their minds and take a meandering but thought provoking ride through the lives of our next generation.
