Now... I found it to be a forcibly silly mixture of nature show (animals attacking animals, some extreme violence here) and stylized cannibal shinnagins. The ending was silly, quite silly indeed, when the white adventure somehow out fought the natives while using their own weapons. Yeah... they've only trained from knee-high on how to use them and a relative stranger to the same would best them in combat almost a dozen times. Yep... very silly indeed. BUT... then again there was Andress nude. I guess that counts for something (evil snicker).
Interestingly this movie was quite controversial in its day. According to Wikipeida, "The film was banned in the UK until 2001 for its graphic violence and considered a "video nasty"."
