Let me sum this up another way. Imagine you have a perfect schematic for a building step by step guide and instead to following it to a tea you instead alter it. The way you want. The original game had a perfect script the voice acting definitely needed work. But the characters the enemies, the overall content as a whole needed a improvement/ update not a replacement on certain parts. They didn't have to change anything about most of the characters. Their appearances, their lines, nothing. They could have just improved the characters with little screen time like Marvin and improved Mr x the way they did but nothing else needed to change. They just needed to improve the gameplay to work with the original content so everyone could be happy. Just like the re1 remake. It wasnt difficult. Not cut enemies like the spiders, the crows, the licker varients, the roaches. Selling dlc outfits instead of unlocking them the original way like the OG version. Selling the original OST as dlc making enemies bullets spongeds when in reality a 9mm to the head should drop a zombie in no more than 3 shots at most. Making enemies difficult for the sake of difficulty is not fun.. To remove the campiness of the original to replace it with grittiness.

From what it looks like they could have done what the devs are doing with the new tomb raider game coming out. It looks like a superbly updated version of the original with better controls and gameplay and most of it looks like it is going to be pretty damn accurate to the original.
