Let me start with the conclusion,
If you like crime stories you should definitely watch this serie, it is really interesting and it is amazingly similar to the real case. If you are looking for high quality in performances, photography, and directing, it is not for you.
I am from Colombia. That crime was so popular from 2010 to 2013, and even in 2019 is not 100% closed. The first positive point is the cast, surprisingly similar to the real people involved in the case, really the actos looks like the twins. Also, the serie did not take any side, just expose the reality according to Colombian law and courts, which is suitable given the circumstances - almost every single colombian person know the case and think Laura and Jessy are guilty-. Sadly, this is not enought, because the greatest point is also the most negative one ,the mayority of actors and actress did not make a good performance, even when they are so similar to real characters. They failed in way to create tension at critical moments (excepting the brother of the main character and Jessy), but the sountrack did not help neither, nor the photography.
