This always seemed to be a problem in ksp. Because alot of people who come from games where its sometimes stunning like Battlefield 4 or COD. They now have this sort of like forced taboo of "I must like the game if its graphically amazing". And KSP Has this fine line of cartoony art style mixed with realism. Its also very moddable which also kinda solves the problem. But for my opinion its amazing once you get in orbit and EVA. The stars,Planet,And spacecraft look amazing.
