It feels like a lot of reviewers know very little about the culture from whence this series came. Thankfully this is not a Hollywood creation. The series is not obliged to conform to the expectations of an American audience, nor is it reliant on the American audience to measure its success. This isn't the first foreign series to get review bombed and still be mega successful on the global level, as indicated elsewhere on the world wide web where people are already asking for a second season.
Let's clarify a couple things. There wasn't as much sex in the series as some of the reviewers would have you believe. They make it sound like it's every 5 minutes. It's not. There are plenty of other things going on.
To be fair, the "voyeur" instances were few. Some were repeated via flashbacks to add additional details that set up upcoming plot twists. Based on that I don't feel feel that the title fit the series overall, but it's a catchy title nonetheless.
Two stars off. One for Ingrid Klug being cast as Rita, and the second star off for the writing for Rita. I've said this in a lot of my reviews: voice inflection and body language are important. Her characterization as Rita was corny, cheesy, and immersion breaking, but that was, in part, because of really bad writing for the character. Since Rita doesn't have much relevance to the overall story to have such a big part in it. I fast forwarded through most of the scenes with her in them.
The beauty in this type of storytelling is that just when you think you've figured out the plot, and who did what, you find out that you haven't figured out anything at all. The story twists and turns with murder, danger, sex, romance, betrayal and intrigue. It keeps you engaged, which is the kind of storytelling that I have grown to love in telenovelas. This one was one of the most complex and detailed that I've ever watched.
If you're familiar with Latin American and Iberian style storytelling you'll enjoy this thoroughly. It's not perfect, but it's really good.
