Well, firstly i think there r few parts not really natural to be connected, even i cant tell where they r....but due to it basing on real cases, i can accept the odd connections; secondly, i think it doesnt present why charlie wanted to kill everyone in that house, there should be more scenes about 1: beach boys rejecting charlie's record makes charlie hate that spot of sharon's house, its a fit to rick yelling at hippies to make hippies turn to rick's house, all about wrong-turn-element. 2: charlie kicking pussycat at home for showing he is the boss and no one can make mess for him, then made a revenge plan....u cant lack charles manson element for once upon time after all, right?....so it is an artificial movie so far, hope quentin can fix the problem in the following extended version....
