The first person to damage Star Wars was George Lucas back in 1997 when he made changes to the Original Trilogy with his Special Editions. In my opinion, Rogue One has been the only half way decent Star Wars movie since then but it can't hold a candle to the original trilogy.
In my opinion, Rogue One was the best Star Wars film since Empire and was also better than ANH, with the Force Awakens coming directly below it and again above both Jedi and ANH. The Last Jedi was better than all other SW films, except arguably Empire, though I still like TLJ more than Empire regardless. So, I guess, you know - everyone has an opinion...
