Parents need to know that this movie is very violent, with a lot of shooting, graphic injuries, and the deaths of important characters. A woman commits suicide when her lover is killed. Characters drink and smoke and one character is drunk. There are mild sexual references, including a homosexual relationship. Some of the Mexican characters could be considered stereotypes, but then so could some of the American characters.
I enjoyed the plot and feel of this movie, too bad they had to ruin it with too much violence, some language and a questionable gay relationship section. It was funny and moved very well, the story was cute.
