I was actually left underwhelmed by this final, simply because the big bad is just going to be a 31st century human that's been writing timelines since reality began, all because of the multiverse?
And yes, I know he is in the comics as a conqueror, but when we've got cosmic beings and the like, the idea of someone so powerful and threatening being a mere human just seems a tad inconceivable.
And how, exactly is a mumtiversal war supposed to transpire onscreen? You just can't portray that kind of thing, unless it's not an actual war, but instead, just a fight between those people.
It'll probably turn out great, at least I hope it will, but I can't help to think that they're trying to fill in some seriously big boots here. How do you truly portray battles not only between universes (an endless amount of them might I add), but also, time itself?
I'm not quite understanding the MCUM either; things change and there's a new branch of reality with new characters of the same characters. This potentially provides the opportunity for endless versions of characters dead or alive to return in other ways - what if?
It's a mess.
