I believe one of the most underrated and seldom discussed elements of the Star Wars Saga is that of slavery, specifically as it pertains both literally and metaphorically to the arc of Anakin Skywalker. Up until TPM, all Anakin knew was a life of slavery, as he had been under the ownership of Watto and other masters in the past. As he's brought into the Jedi Order, he's been literally freed, yes, but he's also imprisoned by the Jedi ways and forced to submerge his true emotions. He clearly resists this system, and feels increasingly manipulated as he grows in strength. His turn to the Dark Side is ostensibly meant to bring him the ultimate freedom by the belief that he will control the galaxy, but in truth he loses everything meaningful to him in the process. All he has is Palpatine, whose bidding he is all too willing to execute for over two decades. All told, in one form or another, Anakin was enslaved his entire life. It is only in his dying moments that he finds genuine freedom, in death.
