This was my first experience of a Spanish Netflix series and I really enjoyed it. The theme is very telenovela, with lots of drama and crisis points, but very entertaining and well paced. The acting is excellent and the characters are believably portrayed. The attention to the period, and the detail in the 1920s hospital setting is amazing. In some episodes I found myself concentrating more on the fixtures of the scene than the acting itself! There are a few authenticity gripes, as other reviewers have noted, particularly with regard to medical procedures but nothing that detracts too heavily. The worst problem is the contrived and badly constructed English audio. I watched with sub titles and English audio, and the audio NEVER matched the wording of the sub titles. Even worse, the audio voices were corny and poorly 'acted'. Very often the audio fell into a modern day American slang, which totally jarred with the elements of the scene. Netflix's shoddy work on the audio is very disappointing as it prevents the series from getting a great rating.
