All right, I've now read/watched the reviews from Destructoid, GameInformer, GameSpot, IGN, RPG Site, USGamer, Twinfinite, EuroGamer, Kotaku, and GamerEscape. Most of the positives each discuss are largely the same: the gameplay system, more in depth characters, world building, and story/plot, etc.
When the reviewers were going over the stuff they were critical of, virtually all had consensus on the technical issues and glitches (the loading textures being the most mentioned) and that the Whispers, particularly their presence/additions during the last couple of chapters, are controversial and/or confusingly implemented.
What I found most interesting about some critiques though, were the differences between the reviews that absolutely love the Remake and think its fabulous and the reviews that like the game and think it's good/great but feel it drags in some areas. And the most common differences largely seemed to be about quality of the side-quests and the extension/addition of gameplay content in the more linear chapters. For some reviewers, the aforementioned content worked for them like the Yakuza or Shenmue series and facilitated more depth and attachment to the world/story, while for others they felt it made the Remake repetitive and or suffering from bloated padding. I found this subjective aspect to very interesting, as I think it reveals a lot about what type of games, particularly RPGs, a person (reviewers in this case) likes.
I've already spoiled myself on a lot the Remake, but I still can't to play it on the 10th.
