Dead Space, arguably one of the best Horror games ever made, was horribly held back by the engines it was made on and the workarounds they had to use. The remake was so much better from a technical standpoint, and is universally regarded as the best way to play it. So yeah, you're right.

The game's not awful, it's just broken. The ridiculous quantity and length of load screens was obviously avoidable. Levels try a lot of things that work fine most of the time, but suffer hilarious bugs for no sane reason. There were surely unaddressed playtester notes about how annoying certain bosses were - both for gameplay, and for repetitive audio barks.

I dunno that it needs a full from-scratch remaster, but it could definitely stand some professional updates. Or drop the assets into a new engine so it can take fresh shaders and feel like it's copying Mario Odyssey instead of Mario Sunshine.
