Now that you mention Ithorians can I ask if anyone knows why Disney has not bought the rights to KOTOR. What other Star Wars story comes closer to Episode V? What other SW story has the epic twist. But I digress. Your point is well taken. I think the problem with SW is there are movies, tv shows, videogames, books, and comics. I have seen all the movies/tv shows/played most videogames/some books that are no longer canon and zero comics. Do I understand more than most? Yes. Do I know all, not even close. But those who only have seen the movies are missing a significant amount of SW lore.
