I thought Rogue One gave a much better lead-in to Episode IV - A New Hope, than Episode III - Revenge of the Sith did. My view anyway is The Phantom Menace, Attack of the Clones and RotS were pretty crap. More to give work to Ewan McGregor than to progress the storyline. The CGI for Peter Cushing was stunning. I couldn't work out if it was CGI or unused footage from the original Star Wars like they used in the flight sequences. His body was played by some Holby City actor but the facial CGI was so real. More stories like Rogue One for me.
