I've finished chapter 5, and it's good. Being a remake, I actually feel that (so far) it's stayed a little too close to the original, and they could have done with a bit more expansion.
That being said, the changes they've made are good. The maps are changed subtly enough that they feel just like the original, even if they're slightly better designed. The asteroid section is fine. I'm not one of the people who absolutely hated the original, but I feel that this replacement could have been a little bit tougher.
The side missions are good, and I think they could have done with more of them (again, as far as I'm up to, they might expand greatly from here on in). The fleshing out of the story is nice.
Overall, it's pretty good.
Interestingly, I read an article saying how DS remake, despite getting all the praise Callisto Protocol didn't, actually runs worse than its competitor. An RTX 4090 can't run DS at 60fps in 4K.
