Bit late to the party, but I finished this last night. I actually started as soon as it came out but I kept putting it down for days at a time which probably isn't a good sign.
I feel similar to
@Cloud (holy crap at all that analysis

) in that I thoroughly enjoyed it but had plenty of issues along the way.
First and foremost this was a nostalgia trip and for that alone I'm happy enough. Seeing all these wonderfully recreated locations, you can tell so much love went into it - the music, but mainly all the subtle things like the daft Johnny escapades, remembering old quotes and scenes, the broken item shop in wall market etc. Even putting some items in places they were originally made me squeal a bit.
It looks phenomenal throughout and most of the characterization and dialogue was spot on.
The bosses were INCREDIBLE. This made up somewhat for the quite boring regular fights. Combat was fun, crazy and varied, but occasionally got a bit too manic and frustrating. Sometimes it felt like nothing but a screen of flashes, explosions and ridiculous leaps to the point I had no idea what I was looking it, but it was enjoyable nonsense and very challenging.
The trouble is I found quite a few parts to be a real slog. Sections that were cut out like climbing the plate wall seem so unimportant but whoever said it, you're right, it feels like such a pivotal moment I was sad to see it replaced. That section where you had to navigate to the top of all the debris to get top side I was bored shitless. It all looks so STUNNING so I hated feeling that way but there was also something mundane and anonymous about it. Likewise with the draggy filler areas like Hojo's lab, the second reactor, the collapsed highway etc (although conversely that last part I enjoyed the attention to detail of bringing the big grab hand from the original into use - but I didn't need to see it about 4 times!). Some of the sections were fine however, train graveyard being the biggest improvement and expanding on the spookiness a lot more.
Sometimes it felt slow and clunky - the whole slipping through alleyways/tight spaces and walking, slowly, over pipes and beams and whatnot, there was so much of this and it got SO tedious, a lot of it felt like following a movie. In fact I've just remembered another section I thought would never end - once you escape the church with Aerith the leaping over houses just goes ON AND ON and the sector 6(?) slums again, had me wishing for it to be over because it got so samey and long-winded.
The sidequests by and large seemed pretty inconsequential and tacked on after thoughts although Angel of the Slums clearly QoL of the year.
I also thought they could have gone bigger and bolder with the colosseum and battle simulator. The Gold Saucer version was a lot more entertaining and I think there should have been options that went beyond 5 battles in.a row, but it's a minor gripe. On the flip side, Hell House was astonishing (again, I can't stress enough how fab these bosses are) and the same with fighting summons which was genius and delightful (and really hard!).
Anyway, sounds like a moan, but only because it's easier to pick up on the negatives. I played mainly to meet an old friend and see what she was like now, and I got that. I think there are games that do this stuff way better, if I'd gone into it as new, I don't think I'd appreciate it so much because realistically it's more of a 7 or 8 out of 10 game for me than a 9 or 10. Yet I'm happy it came and I do admire the detail and sheer bombast of everything. It was a spectacle. Just give us part 2 (of 36) now please!
