It is a cheap piece of bald-faced slapstick comedy that treats the hideous depredations of that sleazy, moronic pair as though they were as full of fun and frolic as the jazz-age cut-ups in Thoroughly Modern Millie... [S]uch ridiculous, camp-tinctured travesties of the kind of people these desperadoes were and of the way people lived in the dusty Southwest back in those barren years might be passed off as candidly commercial movie comedy, nothing more, if the film weren't reddened with blotches of violence of the most grisly sort...This blending of farce with brutal killings is as pointless as it is lacking in taste, since it makes no valid commentary upon the already travestied truth. And it leaves an astonished critic wondering just what purpose Mr. Penn and Mr. Beatty think they serve with this strangely antique, sentimental claptrap.
He was absolutely correct!
