Fred Olen Ray has spent the past 40+ years making exploitation movies. Often the titles identify them as very much not serious movies. Examples are "Beverly Hills Vamp" (starring Britt Ekland as a creature of the night in southern California) and "Evil Toons" (which is basically "Who Framed Roger Rabbit" as a comedy-horror).
So now we have "Piranha Women". The title pretty much explains the plot, and there's some nudity to keep things going. A previous reviewer complained that it focused too much on the boyfriend. I guess that's true, but the movie manages to be entertain the viewer enough so that the focus doesn't matter.
It's a reasonable choice if you're looking for some brain candy. It's probably not widely available; I watched it on Tubi (a streaming service that lets you watch for free).
