Star Wars: The Last Jedi's motifs the to rest of Star Wars

There a few motifs in Star Wars: The Last Jedi that pertain to the other movies in the Star Wars universe.  These motifs pervade the whole Star Wars universe.  They are specific themes that go throughout Star Wars as a whole. 
The first important theme is the "rebels" reference that pervades the Star Wars universe as a whole.  It is mentioned by Finn in the mine scene towards the end of the Last Jedi.  Also, "rebels" reference is mentioned at the very end of the film by Rey to Leia to comfort her that she will be able to form a new "rebel alliance."  In the original trilogy Leia forms the original rebel alliance out of a small band of people then Luke ends up joining the alliance at end of the first movie.  The "rebel "alliance morphs and forms into what it is over time. 
Luke's legendary act at the end of the film is a reference to Luke's overall legendary character arc and a theme of be legendary to save others out of darkness.  Luke's legendary act at the end of the film gave hope to others in the galaxy.  When Luke destroyed the Death Star at the end of New Hope he gave hope to others in the galaxy.  When Luke was able to take down Vader and turn him to light through destroying him and the emperor in the process gave hope to the galaxy.  Luke's other amazing legendary acts too much to mention gave hope to the galaxy.  Lastly, Finn's heroic acts that turned into legendary by Rose's point of view.
The last theme/ motif that pervades Star Wars and the Last Jedi is the them of Hope.  These theme is in all the Star Wars movies.  Throughout the movie the Resistance is on the run from the First Order but Luke's legendary act provides hope to the Resistance and others in the galaxy.  This act keeps the Resistance focused on finding a way to escape the mine they are trapped in.  It is a reminder to ask the question what do we put our hope in? or who do we put our hope in?
