I'll be honest and say that losing the opening 6 seconds doesn't bother me. But, I still feel it's unacceptable and should be addressed by Arrow.
What I'm trying to say is that it didn't ruin the viewing experience for me, like losing 6 seconds of a pivotal gore set piece would have, but I still believe the film should be FULLY intact and I'd like to know why it isn't.
I do wonder if the seconds were removed when editing the final negative, but then reinstated on later home video releases following its theatrical run. Just speculating. I have no idea really. So I'll shut up now.
