It is for people who get taken in by the experience and artistic vision, but the risk with strongly committing to a particular vision is that you’ll put some people off. Aside from its artistic merits, there are definite rough spots from a mechanical and level design perspective. It’s not like e.g. Ocarina of Time, which was also amazing as an experience, and had far fewer rough spots as a game.
That list of things it’s influenced doesn’t make it better while playing. No-one has thought ‘Lost Izalith may be completely tedious and is burning my eyes, but did you know this influenced the makers of Titan Souls’.
