Isn't it about visualising what you want to create in 3D ?
And a matter of the specific thing you're looking at ?
I mean, not even people who like performance art or installations will like everything out there (ok, maybe even they exist too).
I'd say it's visually materialising thoughts, feelings, ideas, stories, concepts, playing with spatiality, the senses/physical sensuality/philosophical sensuality/spiritual sensuality etc, looking at things from different or new angles... sometimes you have to know the concepts behind the thing you are looking at to get a thoughtprocess going or you could end up thinking: "A piece of white wood nailed to the floor, oh great!

", which you could still end up thinking, but I think those things are probably essential to understanding.
Of course, some things are just shit and/or one just doesn't relate.
