Absolutely a great series. A story well told that follows the real world story closely. Roughly 2/3rds of the dialog is appropriately in Spanish .... but herein is the root of the fatal flaw. The English subtitles OFTEN flash on and off too rapidly to read. This is a GREAT distraction. English is my first language and I can read quickly. A minor corollary, I do speak some Spanish and did notice that the English translation, in some cases, has been toned down a bit from the raw terms in the Spanish. Again, great series, well worth watching ... hard to believe that they totally blew the subtitles.
