Hear me out on this one, folks: I feel that it's a shame that the originally planned dialogue at the end of episode 3 between Qui-Gon Jinn's ghost and Yoda was cut. Particularly, the part where Qui-Gon tells Yoda that the key to beating the darks side is Love. Love is the answer. He says that the Sith are looking to achieve immortality through selfishness & cheating death, but they are doing it all wrong. Love and compassion are the keys to it all. He then tells Yoda he will teach him how to retain his identity through the force after death... somthing the Sith will never be able to do. I feel that KEEPING this conversation in the movie would have been a HUGE shot in the arm to the Original Trilogy. Not only because it sheds more light on the Qui-Gon thing and the force ghost stuff, but also because it explains another reason why Yoda would still hide on Dagobah & not go out & help Luke beat Vader & Sidious. Yes, you can argue that Yoda had become "old & weak". Yes, you can say that order 66 was still technically being enfored and Yoda was a recognizable character to the Empire. ...But, I think the story is benefitted immensely if you understand that Yoda & Obi-Wan learned from Qui-Gon that the key to beating the Sith Lords is through Love and compassion. Then it immediately makes sense that Yoda is sending Luke alone, hoping that his compassion & Love for the father he never knew, along with Anakin's Love & compassion for his son will help Vader to snap out of it, where they defeat Sidious together. We all know the story. We all realize that this is how Luke redeems Anakin. ...But, if Qui-Gon's ghost's dialogue was included for someone watching the saga in numerical order for the first time, they would have fewer questions about why Yoda doesn't go with Luke to fight. They would think, "Love is the key. The way for Luke to get through to Vader isn't helped by Yoda going along." What do you think?
