Look, I may be off base with my theory, but it astounds me that people think Jessie and Biggs survive in the timeline that we played through given the evidence.
If you watch the ending again, the meteor of light, or whatever we are going to call it, hits Midgar behind Zack, dust starts falling around him. This same dust is then shown falling in the lower sections of Midgar, and is shown in the scene where we see Biggs wake up and Jessie's gloves on the table. Clear evidence that them living is in the same alternate timeline as Zack.
The sequel could very well show that that timeline ends up with Seph winning very quickly because everyone is alive and that their deaths are just as necessary as the major one later in the story. We just don't know, and to say it is bad now without knowing the payoff is shortsighted. If it turns out that everyone lives because Square just wants happy endings, then we can all complain.
That's pretty much my problem, still. The whole "it creates another reality where everyone survives".
If the original FFVII was about time travel, then I could have accepted the whole Whispers thing in the remake. But one, if not THE biggest point of Final Fantasy VII is that people die, and they stay dead. It's about loss, loss of people, loved ones, and you cannot simply turn back time to bring them back. In the original, Jessie, Biggs and Wedge all die horrible, cruel deaths, Jessie in particular dying while thinking about all the damage her bombs made, and how many people they themselves killed.
In the original, not only do they clear Jessie of all responsibility regarding the bombings (Now Shinra did it themselves), but now she, alongside Biggs, Wedge, and ZACK of all people, survive either in the same reality or an alternate one. Final Fantasy VII Remake (ironically) lost the theme of "loss", and adopted a super cliche context of "defying fate" which many other RPG's have already done. Now all people can be saved by virtue of the main characters being able to see the future.
To me, the change of "loss, and the acceptance of loss" to "let's defy the deities and change our destinies" was terrible. They went from a deep, beautiful concept, to an overused one.
I reiterate, to me, the whole Whispers thing, the ending, the "defying fate" stuff, felt like something an angry fan wrote after playing the original and not liking that it was too tragic. But instead of writing something better, they instead went for the
"and my favorite characters now all survive! Because we all love them, right? So they cannot die!".
I have accepted the ending. I don't like it, but I have accepted it. I DO want to know what follows in the next episode. But right now, while I wanted the Remake to be FVII but WAY better, I can't help but feel that overall, it was way inferior to the original. After I finished the Remake, I immediately began a new playthrough of the original, and each scene seems better there. In the Remake the sense of urgency is lost in many scenes (the attack on the pillar, for one). I was actually baffled that for each GREAT new addition to the story, they seem to make two mistakes.
But that's just my two cents. I want to make clear that I really enjoyed playing the Remake, but I feel it could have been so much more. Remember when everyone was speculating how much of Midgar we would now be able to explore...?
