I do not think there should have been a wholly "faithful" remake. The point of remakes is that it is an opportunity to improve upon the failings of the original, of which FF7 has several glaring faults. The main issue with FF7 is that people only remember the cool dieselpunk dystopia on disc 1. Nobody's favorite part of FF7 is disc 2, which is meandering around the boring overworld with no plot momentum. You are chasing Sephiroth, but you don't really know why. The story is weak. In contrast to having the first remake game being set in the cool diesel punk dystopia of Midgar, SE could have used this opportunity to have set part 2 in the colorful mystical country of Wutai (rather it just being one village), with appealing aesthetics and rewritten the plot to make it more clear and exciting. With FF7R part 1 emphasizing Wutai as a country and building up towards a second war, this is what I expected the second game to be. Instead, it seems that you are once again wandering around doing tedious Western AAA open world stuff in a boring desert.
The remake could have also been an opportunity to make the moment to moment story experience more enjoyable. From what I have heard, the first hour of part 2 is great, and then once you reach the open world stuff it becomes boring. Maybe the remake could have also been an opportunity to rewrite the giant Weapons as mechas that Shinra is developing and you get to hijack them or compromise with Rufus and become a pilot and use them to fight, or something. Basically just make it more fun.
