If those assets were of better quality and if this was a full fledged Capcom game for REmake in first-person, I'd very confidently say that the mansion would be better realized and more encapsulating than it already is. I don't think the perspective shift from third to first-person makes it worse, but instead better. I really don't see how the experience can get more visceral. I'm not opposed to non-first-person, but I do enjoy seeing different perspectives. I know what REmake looks like, now I'd like to experience it in first-person because it breathes in new life to the experience and authenticity.
You'd be making the opposite argument if the series was always in first-person and now suddenly shifted to third-person. The series is not rooted in the camera and obviously changing it would allow for deeper, richer experiences.
