The bad guys of the movie were strongly related to the ELN (a Colombian outlaw group) but that is not wht caused the controversy. The controversy began when people assumed that they refered to Bogotá (Capital of Colombia) as the command center of this outlaw group.
However other people defended their favorite movie studio saying:
"I'm not offended at all... Because it's just a fictional movie not related to real life and is not the first time they show Colombia like this -cough- Mr. and Mrs. Smith."
Other say that is okay they chose the ELN because they chose a lot Al-Qaeda and well... All arabian people aren't bad is like the same situation.
Ironically in Colombia the movie is rated with 4.5 stars and is a total success.
