The original was praised as a masterpiece already, but you said it had many plot holes and lacked contents? Then that mean FFVII on ps1 was an incomplete game and basically, a cash grab? Also, maybe the extra story will synchronize perfectly with the original story, just like FFXV add-on plot for example, FFVIIR will be a true beautiful bonus for a good story that many people already love. Perhaps FFVII fans will love the remake even way more for some too amazing extra stories.

Wait a second.. Zooming in, is that Cloud?

I think in addition to a questionable attitude, he has a point.

Harry Potter is legitimate in having 7 books, because it first appeared that way. 8 movies on the other hand was a problem for some due to the fear of it being stretched thin.

Same thing with The Hobbit - small book, perfectly fine. 3 movies however were reason for concern.

If FF13 came out in one, it would still very much feel like 3 different games, because of different themes, story, game world design and gameplay.

And I think it is a valid concern to have for FF7 to feel like one third of a game. If they make it into a very different game (and gameplay wise and graphically they already did), part 1 could feel like a whole thing. Bit it is a remake and I suspect the story not to change too dramatically.

You are right - remains to be seen if part 1 can stand on its own. But I am sceptical. And I think for good reason.

In one single game, not in multi games that take $60 each game and several next years (if lucky) to come out

Did original FFVII for ps1 was in multi parts like this and the story came out from a book that had 300 pages too? If it did, then it could use this excuse because the story source of the original game was too long for just one game, but it didn't. Apple to Orange. Is the god father movie also a remake which has the story breaks into multi parts of the original movie?

Bad or not, this upcoming game doesn't have the full story of the original game, right?

I have seen dozens of people still do it again and again in Youtube, Neogaf and Resetera. Clearly they despise the idea of breaking the original story into multi parts

Those plot holes could be solved by some addition of the background stories, just some add-on side stories for example, easy peasy.

I said the original has plot holes, and I also said the remake will add more content to flesh out the story to fill up those plot holes. If those people like you said from youtube, neogaf, and resetera have their way then the remake will be a condense game and a huge disappointment.

Can we talk about the screenshots now?

What is the problem with it taking several 60 and years to play it? They aren't entitled to anything, the original game still exist and they can play it whenever they want. And they already made a remaster releasing it in PC with a much higher quality and that was brought to PS4 as well. Sure I would prefer that a remake was just graphic touch up and nothing more, but I won't say it will suck before playing it.

300 pages book as source isn't that big, but I bet that a 3 movies 3h each gave us a much better experience (and yes it took many many many years to be finished) than if it was a 2h single movie.

There is always people complaining about anything and sometimes spamming the same thing in several places. That happened here as well.

And if the game was truly finished and there was nothing to tell them they wouldn't have made sequels, movies and spin-offs to tell those loose threads.

I'm sure a lot of details will be altered heavily. Appears that way from the trailers. But it's possible that they'll still stick to the same outcome for key parts of the story. Character A gets killed in a different way, or by a different person, but they still die in both versions.
Resident Evil 2 Remake is essentially that way. But FF7R is an even more ambition project, so they may very well change some bottom lines completely. Partially to make it a fresh experience, where you don't already hold all the important answers just by having played the original.

They could do things like introduce Yuffie or Vincent in Midgar in Part 1. But I imagine they want to have a number of new party members joining you in the next game as well, so that specifically may not happen. But altering the stage and/or timeline of certain events wouldn't be surprising to me.
And I think there may be incentive to change up some big things, on top of making it a fresh experience to some degree. Over the years they've gotten feedback on some things more than others, or thought things over and may want to explore certain possibilities that weren't in the original. And then there are things like the urban legends of getting the 'white materia' if you do certain things, in order to revive a certain character that I'm sure a lot of people heard about at some point back in the day because it was featured in popular gaming magazines, before internet was really a thing and you could easily find a conclusive answer.

I know a number of games have done this where they put something into the game because it was a popular fan theory. There was a very recent case that escapes me at the moment, but one example is Mortal Kombat. At the end of the original game, one of the developers names, Tobias Boon, appeared backwards in the credits due to a bug. Spelling out Noob Saibot instead. This quickly because a popular fake theory about a secret character you could fight in the game by accomplishing certain tasks. And so the dev team actually made that character and put it in the next game as a secret boss.

Another example is the mistranslation of "Shoryuken" in Street Fighter 2 to "Shen Long", leading to another well known fake rumor and hoax, of a secret character, which inspired the creation of both Akuma and Gouken in later entries.

I didn't think about FF7R Part 2 being possibly the first (since the tradition started) mainline FF game without Biggs and Wedge making an appearance, unless some things change there. So I hope they look at it that way. Or maybe it's an alternate story the developers wanted to explore anyway. But not getting my hopes up there.

When people describe the new additions to FF7 as 'filler content' in a negative connotation, I don't think they generally consider that the process of making the original games was very similar.

First of all, the initial story outline is just the basic story premise, and is missing most of the details. That's where the scenario writer usually 'fills' things in. And he was only brought in after he finished his work on Bahamut Lagoon. The initial plot of Final Fantasy VII was written and re-written more than once. And the idea of pursuing Sephiroth was an idea Nomura came up with later in the process.

And Tifa is a 'filler character', because Aerith was the only heroine of the game until Nomura later suggested they kill her off. Which made them not only have to rethink the future parts of the game without her, but they decided they needed another female character to 'fill' the void. So they invented Tifa because of that.

Aerith was also meant to be Sephiroth's sister at first, then his former love interest. And then they scrapped that idea and instead created Zach for that purpose.
Yuffie and Vincent were nearly scrapped from the game entirely due to time constraints, which lead to them being optional characters, etc.

The point I'm making here is that the process of creating both the story and other parts of the game involves a lot of what people call 'filler'. A lot of back and forth. Changes and adjusting. 
"This town looks pretty good. But the time the player spends here feels a bit lackluster for all the effort we put into it. Let's add a scenario that makes it more interesting. How about Cloud having to cross dress to infiltrate a brothel?"

Then there are all the ideas they wish they could have done in the original, but didn't have time, or didn't think about until afterwards, or decided to go in one direction so they couldn't go in the other. But now they can. Etc.
That's essentially always the case with any artistic line of work. And there are finished scenes and assets put unto the FF7 disc that they for one reason or another never ended up using. We may see some of those things in the Remake.
