well there are people who worked on both shows including the creator so i can understand how you'd see the resemblance

steven universe has at least one episode talking about each of those things. assuredly conversations about different types of abuse are one of the big things in the show. mature topics expressed in a way that is not overly traumatic to children and victims is a big part of why i like the show so much and while the movie is more of an introductory primer to the characters than a direct continuation of the story even it a fair bit deeper than expected(i mean it is implied the villain tried to commit suicide before she chose to go take her anger out on strangers and it wasn't played up as a joke or used to cheaply manipulate the audience)

that is totally something i can see, though i've watched a lot of cartoons when i was younger and you can certainly see similar styles between shows of the same era about as far back as they go XD
