The Ending (spoilers)
Why did Abu Raed go back to the fathers house that night? He was obviously dangerous. If Abu Raed has simply gone back to his own home, the abusive father would have gone insane looking for his family and caused a ruckus ...then Abu Raed could have called the police again.
I found that part highly unbelievable and ludicrous. Ridiculous ending to an otherwise great movie.
