OK, let's get serious here, this movie is just Karyn Kusama's feminist fantasy of sex role reversal and hatred of men put to film.
Spoilers**** Spoilers*******
We have the rejection of motherhood in the beginning where Diana looks down upon the mother and children from above- yes this was planned.
Diana is fairly masculine in appearance and attitude but is showcased as being 'feminine' by the reactions of others outside of her father. So the new definition of 'feminine' gets established as no longer being soft and empathetic but hard, strong, and muscular (masculine).
We have the always present abusive father who also happens to 'support' those bad traditional and 'sexist' roles found in intelligent cultures everywhere across the globe.
We have the 'tiny' effeminate brother, helpless before the might of his sister when she beats down and nearly strangles her father in the kitchen. Tiny boy represents Kusama's acceptable role for a male as he can do nothing but beg his sister who now rules the house.
Lastly we have the ridiculous love interest named after Rocky Balboa's wife, Adrian, who falls in love with Diana but then must fight her in the ring... um yeah right. So in a nutshell Diana beats up all the men in the gym, finds a surrogate father who shows her that, physical reality be damned women can do anything. She then beats her up father, and then beats up her boyfriend who then begs to have her back when it's all over!
Kasuma fantasy is pretty simple- she covets male power, hates men, and despises femininity, so her answer is the fantasy of women becoming men (while still being labeled women) and for men to turn into women or just disappear entirely.
