I frankly are weary of how Disney darkens franchises. Instead of Sleeping Beauty, Maleficent, the evil witch is good and Sleepy Beauty a brat. This is entirely out of Luke Skywalker's character, "You have failed your highness, I am a Jedi like my father before me," (Luke Skywalker, Return of Jedi) to which the Emperor responds, "So be it Jedi" and uses Force Lightning on Luke. Luke was willing to die at hands of Emperor than turn to Dark Side, and it is because Luke believed in good, the Jedi still in Darth Vader, that Vader became Anakin again and destroyed the Dark Lord of the Sith. Contrast that with this new line in The Last of Jedi, "The Jedi must end." Wait what? It is because of Jedi that Vader became Anakin again, that he was redeemed and became a Force Ghost. This is an entire departure from Luke's character. What made Luke unique was that he resisted the allure of Bogan (The Dark Side), in contrast to Darth Vader who gave in.
Frankly, I had hoped Disney was going to make Luke the Master of Yavin IV Temple of the Jedi, but instead they seem to be doing a knock off of the horrible story "Dark Empire (Darkhorse Comics" where Luke turns to the Dark Side. Ugh.
