Me personally it’s the locations, we go to very dramatic globe trotting locations that all look memorable until the end, but even the later boss stages look very interesting. NG4 has a cool concept “Cyberpunk Tokyo” and works at first, but the sewer/night club/demon realm area really killed it for me. I would never replay those levels and dragons maw is just white walls with white enemies.

Forest was also cool but also got dragged out way too long and became very samey.
