Well just like with the most disliked Fallout 4, Original Sin 2 is way too depressing, i get that story requires some drama, but i noticed that there are lots of places where it is not required yet still is.
Not going to explain why this is bad, but personaly that makes the game at least 20% worse. Seriously kids that play such games see more horrible things then some people that actually been at real war. It is a surprise that kids have not yet developed some war related syndroms.
Things you could do to solve it: remove or make an option to remove excessive gore. Remove after battle all the bodies. Remove or set optional gore loots.
