Look, just like Vodacixi has been saying, if you don't think these are any concern to you personally, that's absolutely fine. I like FF7 quite a bit and I think a remake of it isn't a bad idea at all. I wasn't at all impressed with the early footage, these latest trailers have been much more appealing.
However, when you keep saying that a 60-hour game is a good thing, this is a 60-hour game focusing on Midgar. That sounds incredibly dull to me, and sounds like more of the same faults FF15 (a game I thoroughly enjoyed, mind you) had. Also, as has been said in this thread, there's no telling how many parts they're going to be releasing, or how far apart. This could be something that takes 10 years to tell the original FF7 story, and that's just not very interesting to some of us.
Finally, and perhaps most importantly, Square-Enix have already shown us with FF15's second wave of episode DLC that they have absolutely no qualms announcing something in-depth and then going back on it entirely. What guarantee do we have that they're even going to make a part two? They're clearly playing this by ear and hoping, much like a kickstarter, that things will pay for themselves throughout development, thereby releasing it piece by piece. What if it doesn't? Having one or two episodes that cut off at the halfway point would be an incredible shame and this is a very real risk, clearly, since FF15 just went through the very same thing (albeit on a smaller scale) and got its story cut short entirely with three episodes meant to tie up the narrative never released or really talked about again.
I think the episodic approach they're taking is disastruous because it has no accountability and the only thing it promotes is extreme bloating. I don't want to spend 60 hours in Midgar because I don't think Midgar can be interesting for that long. Maybe you do, and that's fine. But disregarding every critique against this approach as "overblown hate" isn't doing you, Square-Enix or anyone any favours. These are real concerns. If they don't bother you, that's okay. But they bother a lot of us.
