Everyone has a past. We cannot change it but the last thing we should do is living in the past to escape the present,thus miss the chance to possess a different future.
Ronnie is a pervert. The chinas of little children which appears in the first scene and are destroyed in the last can serve as a clue. Ronnie broke them,as if by doing so he could not be no more pervert and even castrate himself. He wants to be his mother's good boy and he cries like one after his mother's dead in the park where Sarah meets him in the dark,forgets his being pervert and talks to him.
"Do you need help?"
"Yes. She's gone. She's gone."
"Sorry,who's gone?"
"Mummy. She loves me. She's the only one."
Conversation stops here when Sarah finds her daughter could be seen no where.These two incidents,which she should be thank for,pull her out of fantasy,fantasy which is so fragile that any interruption could abort it.
Sarah,in my opinion,is not a feminist as she considers herself secretly as Madame Bovary who struggles in her life with a man she bears no love,but a escapist using her obscene husband as a perfect excuse to start a relationship with Brad,the man that she kissed in the park and forever lingers on her mind.
Brad,the only man who shows up in the park during weekdays,is totally a loser except his good looking and masculine build.He fails in the bar test for twice and deems it as a way to oppose his beautiful wife whose dominant state shows clearly even in the photo ,her shadow enveloping the daunted husband behind her.Brad's simmering manly feature waits for some catalysts to blaze it up.Sarah's love is one and the other is the affirmation of his manhood through the soccer game. The combination of these two when Sarah cheers up for his triumph in the game stimulate his impulse to run away with her.But Brad always holds a wrong conception of manhood until he takes the challenge to skate ,injure himself ,realize the irreversible youth and finally face up with the reality with responsibility.
Stories with transgressions and degenerations prefer this kind of turning points while I have no liking and always with a doubt. Can they really get their life back on track?
