This is a very well-made dark, sarcastic allegory of the security situation in northern Mexico.  Imagine Scarface and Herod’s law having a child while listening to narcocorridos.  Not for the faint of heart, and definitely not for anyone under 15 years old.  I bought the DVD recently, but if you happen to come across it in a film festival or on TV don’t miss it.  Definitely the Mexican hit of 2010.
