Right, I did not realise this was out on dvd, I watched the video a couple of times. I disagree with the blurb, Standahl Bergman, the eponymus She, does not try to rule the post nuclear holocuast world (or america, as we know it), rather she falls in love with one of the two leading males and agrees to help him rescue his sister from the Norks (New Yorkers-get it?)who carry her off.
She is a goddess who is imortal via some dodgy bathing in a radioactive pool (replete with gartuitous nudity) and some form of regeneration.
As she travels out across the wasteland she meets some other cultures,a group of mutants who literally fall apart, a fundamentalist, Orwelian society built around a male mutant andt a scientist who attempts to experiment on them. All are dealt with to a clagourous rock score (featuring Maggie Bell at her raucous best).
Arriving at Nork they have to deal with a man who can multiply himself then rescue the girl. The end is lame brain and at odds with the continuity of the plot.
To conclude, I'd buy it cuase I like Standahl Bergman. On a more critical level I think on the whole it works it is part of the post star wars/mad max scifi 80's exploitation boom. There are some nice touches-the multiple man, the Orwellian state and the acting isn't bad. I think it looks good too.
