It's a parody!
It's parodying the process of transforming women's bodies - it's not advocating it as so many reviewers seem to believe. Was the plastic packaging with the barcode or the excessive blood or the misogynistic language or the total skin transplant not clear enough for you?
Anyway - this is the best parody of this type I've seen - it's lack of animation and simplicity were what kept the score from being higher. There's nothing like a no-holds-barred parody!
