I was the oposite. The chronological version freaked the hell out of me, affected me emotionally. Because you start of rooting for the girl, hoping she get's clear, only to see her fall, and to watch the horror/terror of her family, the panic and evolution (degradation?) of their situation, terror and doom for some reason just freaked the hell out of me.
The original is clever and wonderfully executed, but for emotional impact, well the first version made me want to rush home, hug the family and secure the doors.
