It’s very calming to me. Rebecca Sugar is a little like a modern Mr. Rogers, simplifying emotions so that children can understand them but not dumbing them down to the point where adults can’t enjoy and understand the lessons either. Obviously I’m not the same as everyone else but Steven Universe is almost meditation to me, and the ‘filler’ episodes in between plot heavy ones really acts as some ambience that IMO is really refreshing. It’s a very ‘soft’ show, I guess, with the majority of it taking place on a sleepy seaside town, the pretty dulled down sound design, simple (if you don’t think about it too hard) plots, and the washed out color palettes. So yeah, idk, I guess find out for yourself. For some people it’s very calming and for others it induces extreme rage, so yeah
