One thing about ROTJ that’s often overlooked is how it thematically sets up Luke and Leia’s sibling relationship.
In ESB Luke rushed off hotheadedly on his own to save his friends, and got his right hand cut off by Vader as a result. In ROTJ Leia rushes off hotheadedly on her own to save Han, and is unmasked and implicitly raped by Jabba as a result.
Skywalker hotbloodedness in both cases. But since the Leia bit of that parallel is told mostly through implication, few viewers pick up on it.
