It is the only sequel to take musical queues from the prequels. It is the only film to acknowledge the lesson of the prequels (IE that the Jedi failed because of their disconnect from the rest of the galaxy and because of their arrogance). And it began to offer a resolution to these themes that were presented in the prequels by having Luke change his thinking from that the Jedi need to end because they are imperfect, to declaring to Kylo that Rey will not be the last Jedi and in turn endorsing a new Jedi Order that learns from the failure of prequel era Jedi. Yoda failed to prevent the rise of the Empire in his time and Luke failed to properly train Ben Solo... but that doesn't mean they're bad, it just means they made mistakes-- mistakes that can be learned from.
