I started watching this today and as the series progressed I started to feel there was a bit too much melodrama in this; I checked a number of reviews online and found out a lot of reviewers were feeling the same, characterizing this as a "soap opera". There are some aspects which add a bit of interest, like the fake interviews framing the story, or the hints about some kind of conspiracy in the University besides the main story about the car accident, but by chapter 3 these are still too vague to justify continuing watching this. Of course, I always enjoy series showing Madrid, my city, and its region, although as it often happens some of the houses shown are of an incredibly high status which is not very realistic in this academic context, as happens also with the lobby of the hospital or the facilities of the private University; it's all too shiny and expensive and does not reflect very well life in contemporary Spain.
Natalia Verbeke is a bit out of place in this production, and what I find really interesting is the actor playing Daniel, since his facial expression and demeanour are so radically different to his best known role as Martin in "Laura's mysteries", to the point of making him difficult to recognize. The police investigator is for me the best and most realistic character, with a very credible Madrid accent.
All in all, a series to pass the time of the day with good production values but with a not all too interesting script.
