If a game is trying to portray a realistic rendering style, animations go a long way. HB2 wouldn't look as good as it did if it wasn't animated as well. Imagine that fidelity running with Quantic Dreams animations, it would pull you out of the experience immediately.
South of Midnight is going for a completely different artistic and animation style altogether.
Animations are not really worse than many other games, this is not a AAA big project, if slimy is right, this is a small studio effort and i don't think konami is wasting that much money, you have to adjust your expeactations.
Also, after the shitshow that twin snakes received for modernizing mgs1 other than the graphic, you think konami want to piss off old mgs fans? it's better to do a 1:1 remake that play the same with the same animations.
It's not only midnight that is going for a particular style, the remake is also going for a ps2 game style, this is not a fully modern game, just the graphic is.
And let me say it again, people were talking about shadows or hell even starfield looking nextgen, and those games have a lot of crappy animations, so why animations are so important when we judge the remake?
I really don't think midnight look any better than the remake from a graphical standpoint, and like i said, the animations are not even that great during gameplay.
