Politics aside, the main character is spunky, sweet, and HILARIOUS
Had they not found her late in the casting process, the film would likely have been decent but not nearly as great.
Of course, she benefits from a strong script as well (the character being modelled after the director's niece, who is always scheming to get money some way or other). I think my favourite moment of all was when her friend offers her ten dinars or whatever it was if she will stop crying. She does not yet uncover her face, but with perfect comic timing holds out her open hand for the cash! LOL
