I like it, they broke away from the old sci-fi serial sounding titles of the previous second entries. This title sounds more like a chapter in a book, which I say is kinda fitting for the second to last installment of the overall Skywalker saga. The title of course refers to the self exiled Jedi Master who was finally located at the end of the previous film, Luke Skywalker, who was referenced as such in Episode VII's opening crawl and a couple times in the movie.
I really loved that the teaser poster is nearly identical to the teaser poster from two years ago just with a different color logo and the new title, well done. Another great touch is the color red for the Star Wars logo, which to a lot of long time Star Wars fans is meant to invoke memories of 1983's Return of The Jedi which a great amount of it's advertising and merchandise feature an all red logo. A nice connection signifying that after the death of The Emperor Luke thought he could create a new Jedi Order, only to have tragedy strike once again making him The Last Jedi as Yoda told him he was before his death.
