Rubbish. This is the worst excuse I've heard yet. Seriously. It's called "time travel" not "time dimension". You're now just making things up as you go along.
In many fantasy tales, time passes differently while the person is away in some other world/realm/universe/reality. Many fairy tales, The Lion The Witch and The Wardrobe, etc. Although this was the same world but in the past, there's still no factual statement as to how time passes.
Just as there is no factual statement about many other fantastical elements of the story.
It wasn't spelled out, but given that Kitty would otherwise be holding on for days, which seems unlikely, one assumption is that only a day at most passed in the future.
Filmmakers can make up any rules they like about the mechanics of time travel since it hasn't yet been achieved, as far as we know.
No, it's the other way around, rather. I don't care about whether or not people think the various plot contrivances are plausible. I only care about defending my opinions.
I have already accepted your opinions.
It was both. btw they say an inability to admit when one is wrong is a sign of character weakness...
I'm not wrong. I asked whether you had some underlying agenda.
It's not about whether you know I don't think it's perfect, it's about whether you accept it. You clearly cannot. And why do you keep saying 'we'? Stop hiding behind other people and take responsibility for how you feel.
A few posts above this I said: "But I accept that you can't accept this element of the story. That's fine. But others of us have our own reasonings for why we DO accept it."
So I do accept it. But still you keep ignoring it, driven by your own blind attitude...
This is a fan retcon. Much like your laughable "time moves differently in 70s" argument

t:
It's not a retcon, it's a point for discussion. Especially since it wasn't stated in the movie how much he knew about the past during the time he was in a depressed state.
So, to conclude, I do accept that you have issues with this part of the story. But I do not share those issues. And I don't find myself liking your attitude very much at all.
