The movie's an unexpected end-of-summer tonic: a trash guilty pleasure with a healthy (if really violent) sense of outrage. It's also Rodriguez's freest movie yet, and possibly his best.
"Machete" is gratuitously smutty, sadistically violent, politically aware and somehow also politically incorrect. Put more succinctly, it is awesome, and delivers every goofy gory guilty pleasure "The Expendables" was supposed to but did not.
It's basically a one-joke exercise heading toward the inevitable big battle between vigilantes and Mexicans. There's lots of gore, flesh and fun along the way, but it gets repetitious.
