@SaurabhAV: Yeah, it's the central theme of the movie that actualization comes from within. Rey thinks her identity is pinned to her heritage and legacy, but the dark mirror cave shows her who she is: just Rey. It's a reversal of the cave scene from Empire, where Yoda tells Luke that the only thing waiting in the cave is what he brings with him, and he sees himself in Vader's mask, suggesting his legacy.
Luke says, "The Jedi do not own the force." Yoda says, in the most important thematic lines of the film, "The greatest burden of masters, this is. We are what they must grow beyond." Growth means learning from the past and becoming something different, not just repeating it. In a way, this movie serves as the perfect commentary on The Force Awakens and its endless rehashing. Instead, The Last Jedi takes the basic framework of Empire Strikes Back and then weaves a new story around it.
Have high hopes for The Last Jedi. Not being an Abrams film, it might actually be good.
Initial feedback for The Force Awakens was also very strong. It took a little while for the dominant critique to emerge that the movie was just a rehash of previous Star Wars films with nothing new to say or add. Hopefully they took that to heart, and this one is more like Rogue One than TFA.
@sinister1989: It surprises me that so many movies screw the pooch on Batman when the formula is so obvious. Take equal parts Sherlock Holmes, Bruce Lee, James Bond, and Dracula. Mix well. Add clowns to taste. Voila!
