This is a review for the whole season 2 without giving away any spoilers.
Season 1 was interesting but this season takes it to a whole new level. There are so many twist and turns to make it fun to watch but if you are the type that notices plot holes and plot inconsistencies then you will be very frustrated. My wife and I finally decided that we had to stop pausing the show to discuss plot issues or else we would never finish the season!
I don't understand why on Netflix it is rated MA. There is no swearing or nudity. There was a slight bit of that in season 1 in one shot but alas no more after that. As a guy, if it wasn't for the characters of Eva, Casandra, Veronica and Caroline this could have been a very difficult show to watch.
The acting seems very shallow but then again it was originally done in Spanish so I am sure a lot gets lost with English dubbing.
It looks like there will be a season 3 and 4. This season ends the story quite nicely. Just don't pay attention to all the plot holes and inconsistencies!
