Part of the fun of watching a Russ Meyer movie is sitting in mind-boggling disbelief at just how sexist & deranged it is, then going with the flow as you escape into his voluptuous pre-silicone dreamworld. Misogyny isn't really the word, as you can imagine the old sleazeball worshipping these women & doing anything for them while he's filming them bouncing around.
Supervixens, however, is just plain nasty, due to the one scene in which Super-Angel (the running joke is that all the women have the Super- prefix to their names) is kicked to death & electrocuted in a bathtub by Charles Napier's impotent cop. Not funny. Doesn't help that Super-Angel's character is set up as being somehow deserving of it.
No, not funny at all, even if you're used to the Russ Meyer school of sensitivity. It belongs in a 1980's splatter film, & leaves a nasty taste in the mouth for the rest of the film, which is pretty ordinary until Charles Napier turns up again & torments Super-Angel's later re-incarnation, Supervixen, in a way that would be amusing if you could only forget his earlier scene.
See Beyond The Valley Of The Dolls instead.
