I have to commend Rogue One for the attempt (as well as the balls to end it the way it did), but the technology is still not there, especially when you place real actors with digital recreations, it broke the movie for me at times.
Hearing that Disney and Lucas Art aren't going to CGI the recently deceased Carrie Fisher in any further Star Wars movies makes me feel good moving forward. However I am totally not against recasting and I don't feel that would be disrespectful. If Leia is that important to the story for EP IX as rumored, it would be more of a classic film making approach to keep the story and character integral to the film as opposed to "killing off screen." I'm pretty sure there is an actress out there that could not only do the part justice, but keep the character alive in Carrie's name.
