I didn't vote in the poll because there wasn't an option that I fully agreed with, lol. Can there be a poll option for 'I don't know what to think?' or 'It's complicated!' It's been two weeks since I found out about the ending, and I still can't fully settle on my feelings on it.
I think the ending is an interesting thought experiment, and it could be compelling if done with nuance and restraint, but nuance and restraint has been hard to find in both Nomura and Toriyama's games for a lonnnnnnng time, along with Nojima's writing. FFVIIR was sorely lacking in subtlety in general, so it doesn't inspire confidence going forward. I personally haven't enjoyed a Nomura/Toriyama/Nojima/Kitase collaborative effort since FFX without a fuckton of caveats -- ditto to a Nomura/Nojima director/writer combination since KH1. I also literally just played a version of FFVIIR's goddamn premise with KH3, too, which again doesn't inspire confidence.
To elaborate further, I think the Whispers were a genuinely interesting concept in theory, even if I think the potential meta commentary is self-indulgent. In execution, though, between their character designs and their continual use in disrupting plot beats, they came off as silly, when they could have intriguing if used more sparingly. (The character design looking like ghostly wrinkled penises will never not be hilarious to me, either, especially when they look up at characters, leaned over characters, and the one came out of Barret's chest. They look better on the steelbook being smoky shapeless shadows.)
I think Sephiroth knowing the events of the original game is interesting, too, along with how that effects Aerith in turn, because as far as I can see, it's now to his benefit if she stays alive. It also seems like he's manipulated the party into destroying the Whispers also to his benefit, which now gives him more of a free reign. Again, I like these ideas in theory, but it's just the execution of it that was way over the top. We see a lot of Sephiroth in FFVIIR, but he and Jenova are less fleshed out than they were at the original game by this point, and that's considering we don't see Sephiroth in a physical form until the cargo ship in the original!
...Zack is a whole clusterfuck that I don't even know where to begin with. I again hope restraint is used regarding his character, but... hope springs eternal. (My crack theory is that if we do see Zack in an alternate timeline, he'll team up with Biggs, Wedge, and Jessie. I don't want this to happen, mind you.)
A best case scenario for me going forward would be sticking broadly to the plot beats of the original game like 90% of Part 1 did, with some remixes of plot beats or fleshing out the world and characters in new ways, like with Jessie. I can't imagine we'll see huge changes regarding the subplots of the original cast (eg. Barret, Red, Yuffie, Vincent, Cid), even if they're remixed and the placement is different. I'd be interested in having more time with Aerith, and potentially pushing her death back to the Northern Crater, but I'm still not sure if Sephiroth will want her dead or not.
Positively, I like that that FFVIIR being a stealth sequel gives a sanctity to the original game, and doesn't replace it. I think FFVIIR shines at characterization, but the original game has a far stronger and tightly plotted story, so there is still very much an incentive to revisit the original, along with the original game's soundtrack and pre-rendered backgrounds.
On the other hand, I am still disappointed about FFVIIR being a stealth sequel, too, because I think the FFVIIR team could have done a solid job remaking the original without excessive changes -- which they did do for the most part, until the final chapter. The combat is wonderful, the characters are beautifully realized (Aerith has her personality again!), the soundtrack is lovely, and I've really enjoyed the English localization. The game has had my favorite cutscene direction in an FF game since FFXII, and one of my favorite FF single-player English localizations since FFXII and WoFF. Whilst I have my issues with padding in certain chapters (I classify padding as long periods of time with no character/plot/world building development), the highs of some chapters and most of the boss fights are wonderful.
I ultimately also don't trust that FFVIIR has something to say outside of wooo, meta commentary about defying fan expectations! Much applause. For me, the themes of the original game were life and death, identity, and the environmentalism, and there ended up being a wonderful synergy between all of these. They're still kinda there, but defying fate ended up being the focus of Part 1, like with the FFXIII trilogy and the KH games. If Yoko Taro had been remaking FFVII in a similar stealth sequel direction, I would be genuinely terrified* of the result, but I trust and respect his track record, and how thoroughly he explores the themes he establishes for each game.
*The Taro approach to fan expectations would be: Okay, you want Aerith and Zack to live? Then you get to see everyone else die violently, traumatically, and horribly. Be careful what you wish for!
I'm hoping some post-release interviews and the Ultimania provide some clarity on the direction FFVIIR will take going forward, but they probably won't, and we'll be arguing about the Zack/Stamp chip bag for the next 3-4 years. Help.
TL;DR: I like the idea of the ending in theory, but I haven't liked the execution of it thus far, and am concerned about how the ideas will be implemented going forward based on the track record of those involved.
