Some people believe that Lucas made a good decision in selling the franchise to Disney because it allowed for the continuation of the Star Wars legacy and brought in new and fresh ideas to the franchise.
Disney has released several successful Star Wars movies since the acquisition, including The Force Awakens, Rogue One, and The Last Jedi. Additionally, Disney has expanded the Star Wars universe through TV shows like The Mandalorian and books and comics.
However, others have criticized the sale, arguing that the Disney movies have not lived up to the high standards set by the original trilogy and have failed to capture the magic and essence of the original films. Some fans have also expressed disappointment with the direction of the franchise and feel that Disney has prioritized profits over storytelling.
In the end, whether or not George Lucas made a good decision in selling the Star Wars franchise to Disney is a matter of personal opinion. It is clear, however, that the sale has had a significant impact on the Star Wars universe and the way in which it is consumed by fans.
