Ok, all I remember about it was there were 3 characters, a boy his dad and his mum, the boys dad was a drunk or something and kept beating up him and his mum, so one day the boy did something wrong and his dad was beating him up and then his mum came in to try and stop him but then the dad killed the mum and then the boy came in and killed the dad...
I think I saw it in 2003...Anyway, any help is appreciated...
