The true level of violence in Mexico
If anything the movie falls short on representing the level of violence we live in the country.
Ever since 2010 several buses traveling to the north of Mexico (and into the US). Have gone missing. There been findings where the buses are buried, and authorities exhumate the bus without telling the press about it. Where did the bodies go? mass graves... some mass graves have been found.
The women were raped and murdered, the kids were put on barrel with acid, elder people and cripples were forced to lie on the road while the bus crushed them. You think Im making this up? look up Comandante Kilo and the 275 mass grave they found on San Fernando, Tamaulipas.
....And the abled men? they were forced to a deathmatch with each other (or else they'd torture them and kill them) the winner of the deathmatch joined the cartel (forced to). Only to be send to suicide missions.
