This pretty much sums this up.

For me, if they don't try to keep the battle/materia system basically the same (maybe have the option of turning off the summons animation) then they shouldn't call it a FF7 remake, but instead have it be another entry like Crisis Core. I think by calling it a remake will give them flexibility with the game, but it shouldn't come at the expense of a function that was the core part of the original experience...IMO.
I would think visuals are subjective to each person. What I feel is visually immersive, may not be to somebody else. Final Fantasy 6 is still visually immersive to me, but there is definitely people that would not agree.
Gh05t-The director responsible for that was let go, and since then the game has improved by leaps and bounds. The intial launch was a disappointment, but they have fully turned the game around.
