Demon's Souls (2020) is just OG Demon's Souls but prettier. Bluepoint keep all the jank the make the original miserable experience to play, while also overhauling/redesign that stray further from the original artstyle.
BonfireVN makes a lot of comparison video of OG and Remake, and most of the redesign turn everything into grotesque monster (like the Fat Official, and The Adjudicator for example).
If anything, it should be the reverse, keep all the artstyle the same and pretend you're trying to trace someone's work, while overhauling the gameplay, the fans would be more satisfied that way.
