I think that's exactly what I find the most disheartening about it all. The feeling that all of the excellent hard work done in this Remake of replicating story beats, of creative expansion, of adaptation and modernization, of vibrant characterization... that all of those positive feelings are overshadowed by... I mean, literal shadow creatures that one could argue represent the people who wanted a faithful remake. It's just so weird.
One doesn't have to let shadow creatures overshadow anything. If the replicating story beats, creative expansion, adaptation and modernization, of vibrant characterization of what was expected from the OG is what you enjoyed and wished for. Congratulations, you received it. It's all is still there. Just because the unknown holds unquantified and immeasurable potential to swing either way doesn't change the fact that what was given and presented exists and was achieved. It's the fundamental of spontaneity and ambiguity. The Remake is not simply a "safe" endeavor anymore.
The thing is, I don't know that you can say that for sure. This ending seems deliberately enigmatic and vague to leave things open. The characters are manipulated into defeating the force that protects the story that people know and love. Again, it's just so weird. Not good, not bad, not ugly, but weird. It leaves me with an exasperated "but why?", rather than the excited "ooh, why?" that it might be going for.
I mean, yeah. That's accurate. However, I don't believe it will deviate so far that it would literally become completely unrecognizable. Yes, there is potential for change. No, I don't think it's gonna be changes that fundamentally re-write the metaphorical DNA of the story, since there's clearly a path and course direction they're steering towards. After all this is their Remake, but creative freedom is obviously the message and, I don't have any reason to mistrust it.
No, the second part of your sentence is a counterpoint to the accusation that's raised of people wanting a 1:1 retread. I feel like people are constantly saying they're okay with expanding the original story. That was the entire argument upon which the team tried to sell us on the idea that this first game would only be Midgar - that they'd embellish the story and that they'd show us "more of Midgar" than the original game. And I'm not saying this game hasn't done that. Even if the people complaining about busywork sidequests are the same people complaining about time ghosts, those are two different issues. One can have more than one issue with a work without those necessarily being ingrained.
They did expand the original story. They expanded it and stayed true to it's pacing and fundamentals. Midgar was expanded and the game is at least 30 hours, a sizeable length of a full length RPG. What you're talking about sounds like ultimate filler and busy work. There's absolutely zero reason to go to other sectors that have no bearing, relevance or means of travel. Especially when there's plenty of room and adaption space for what is part of the story. Cloud and the others can't move freely as they wish throughout Midgar. It's a risk as is using the means they do already. The "more than one issue" is contradictory. Less filler, but more... Pacing-muddling filler?
We've seen that already. FFXV's side quests and open world lay out run the gamut from the jovial and endearing, to the mundane and mediocre. And it wrecks the pacing of it's narrative at times. VII doesn't
need that when it has fertile ground within the soil of it's setting, that lets it adhere to the plot's progression.
Changing the pacing of a story through bonus content is a different concern than adding literal time ghosts to make sure the story doesn't change. But it becomes the same concern of course when we wonder: if they hadn't added all this extra stuff, would they've instead been able to explore more of the original story?
No, because the original story
has been explored and expanded. The entirety of the climax with the Arbiters of Fate happened at the
conclusion. It punctuates what already has been done. So I'm not sure what supposed further exploration you could've asked for, save for random FFXV road tripping that has Cloud and the others riding through Midgar in their stolen vehicles without form or function.
Why can't there be a way to visit every sector of the city? It would still be more believable than spooky magical time ghosts, so whatever the reason was for the stifling linearity it certainly wasn't due to being faithful to the original story. Also the coliseum wasn't really a sidequest since it's mandatory for the story to progress. The actual optional side quests themselves were standard RPG stuff like I already said, and the most I can say is that some of them did add a tiny bit to the worldbuilding but that's it.
So why
would they visit every sector? Every moment they move freely above the plate puts them at risk for capture or confrontation with Shinra. There is no freedom of movement when they have to rely on fake IDs and Shinra's omnipresent security looking for them 24/7. That pacing and portrayal doesn't make any sense and is shoehorning an openworld gameplay model in a clearly linear, narrative driven story. And it certainly is less believable than the Arbiters because at least the ghosts result from the magical element of the setting and Sephiroth's supernatural meddling, instead of the characters seemingly doing all manner of road tripping amidst a crisis and manhunt.
And this is ultimately an RPG. So the story will be told through RPG methods. I don't get what you were expecting. The continued questing of the coliseum is not mandatory, and you can also explore more of Wall Market and see the direction of that location as well. There's not a lack of anything to do to see an expanded and fleshed-out Midgar. It's NPCs and quests are written to express the distinct flavor and atmosphere of the slums. So there's certainly more than just a tiny bit. The actual exposition that illustrated the knowledge of Planet Theory amongst the people and how they've been so coddled and accommodated by Shinra
they simply don't care, is a pretty telling perspective and fascinating examining of the public view of AVALANCHE. Likewise Kyrie and her motivation being a thief, hustler and liar also give a unique look into how life in the slums unfold. There's
a lot of expansion there that's beyond just rote fetch-quests.
