At this point 'Beneath..' appears to be Russ Meyer's last movie, which is a pity. A pity because we could do with his invention and energy and ideas to liven up our dull movie going lives, and also a pity because it isn't one of his best efforts.
Meyer's two movies prior to this one - 'Supervixens' and 'Up!' - are two of his best ever, and don't receive the attention they deserve. 'Beneath..' follows a similar format to those two classics but does so with more coarseness and less fun. Meyer takes advantage of the more liberal censorship laws of the late 70s and makes his most explicit movie yet, but loses much of his sense of smutty joyfulness.
The one thing that saves this movie is the exuberant performance from the dynamic Kitten Natividad. If you are a fan of Kitten and her sensational body then this is the movie for you! Otherwise I could name at least a half a dozen Meyer movies to watch before this one. A disappointment this, but still has enough glimpses of Meyer's genius to make it worth a look.
