I would like to comment on Felipe's opinion about this movie. He says that in Mexico (also my country) the poor people are not as poor as shown in the movie... well, I disagree. In Mexico you can find people even poorer without even shacks falling into pieces, homeless living in the streets, under bridges. He also says the riches are not that rich, and I can't conceive he states that. There are some really wealthy families living in El Pedregal, Santa Fe, Las Lomas; and some politician families are, without any doubt, as rich as they want. And I won't even argue the third state about politicians being THAT corrupt, because statistics talk for themselves and Mexico is shown as the 6° most corrupt country in LA and the 64° in the World (according to the Corruption Perception Index of year 2004).
And yes, the movie is barely OK, but Mexican cinema industry is getting better. And this movie is finally depicting the general situation in Mexico in a funny way, not like other really bad, sad movies. I recommend everyone to see the movie, enjoy it, and definitely, like Felipe says, don't think that's the situation in all the country, although it is in some parts. Watch the movie, and think it is telling just another story that could happen anywhere.
