Yeah, this looks like one of those cases where improving the problems of the original irons flat some of its old charm; the chunky framerate could make the sprite characters seem creepy, and the grainy texture display really gave the lighting effects stark contrast and dimensionality. It's a rare case where "better" isn't better because some of the technical deficiencies played into the highs of the original experience.
(*Another one with that "better
≠ better" feeling for me is PS2 Medal of Honor Frontline; when they "remastered" it for PS3, it felt like a normal game, not this incredible epic that was straining the console to its metal to try to render the chaos and expanse of that harrowing beach assault.)
In other parts of the trailer, Exhumed Remastered looks fine and like a lot of fun, so maybe you can get used to it or there's plusses and minuses to the conversion and that's just part of its own take on things. NightDive usually does trustworthy work, so I don't want to pass judgment, but looking at the trailer kind of made me still want to track down an old PlayStation copy or boot up a Saturn emulator and see this as it was in its prime.
