Clearly meant to be a good time, but the constant, looming shadow of the period's misogyny keeps it from being a timeless entertainment. (There's one moment at the end where it's played for laughs that's hard to shake.) But hey, fights are won not by fists but by lyrics, which is how it should be.
A film whose success has probably a lot to do with the ubiquity of its eponymous song. Technically it's well made, and overall it's a very witty story. It suffers from some obtuse machismo, especially towards the end. But in many ways, it's enjoyable and for obvious reasons, it's considered the first Mexican blockbuster.
