Low budget, formulaic - and lots of fun, especially for the 'camp' fans. Unlike a lot of 'camp' film 'classics,' there's nothing offensive about this one, which may explain its low rating, as camp fans sometimes demand the tasteless and forget what entertainment used to be about.
It's not stupid, its just a light working class Tarzan-type pic with humor, '40s style knockabout action, a good guy finding redemption in the arms of a beautiful and innocent young woman, a nasty villain, and babes. The 'natives' are not treated with any racist derision, by the way, which makes the whole outing harmless fun 'for the whole family.' Defintitely the type of film you would like to see on late night TV just before hitting the sack.
