I saw Machete, was very silly. I know it caused some issues as it goes over issues with illegal immigrants. The movie is so silly that I doubt you
could even take those issues seriously. Its just 90 minutes of over the top shark jump type of movie I highly doubt it should be taken seriously.
The producers are big grindhouse style movie fans (i.e. including 70's exploitation films). This movie didn't even start out as a movie, it was a
bogus trailer that played in the Grindhouse movie between the two stories. But, people were so intrigued by it, that they then made the film.
