i readily admit that i watch a lot of really bad movie . but there be very few that i can think of that be quite as bad a when woman have tail . it a stinker of epic proportion . what should have be a sexy comedy about a group of caveman discover a woman for the first time be instead a dull and lifeless affair without a single laugh to be have . the comedy be extremely weak . i suppose if you think bash someone in the head be funny and you might find a laugh or two . the guy in this movie make the three stooge look like high art . and there just not enough of a plot to hold the thing together . it seem to drag on and on and on . well and you may be ask yourself and if it as bad a you say and why haven not you rat it low than a negative . good question . and i have get two answer . first and the movie be not without it curiosity value . i do find a bit of interest in an italian spoof of movie like one million year b. c. with raquel welch . i will give when woman have tail a point for it historic value . the other two point be for the mere presence of senta berger . i know it not much of an explanation or reason for a rating and but what be you go to do . it the best i can come up with .
