I would say that George Lucas is and was not a good director or writer. During the debate, I will mostly be talking about the Star Wars Franchise, but will include other projects as well. Without even needing to look it up, we all know how hated the Star Wars prequels are, especially in comparison to the original trilogy. We also know that George Lucas was the director and writer of the first in that original trilogy, as well as the director, writer and executive producer (among other positions) of the three films in the prequel trilogy. However, according to multiple articles on the subject of George's film-making skills, he wasn't good at directing his actors (1), writing his films (2), and has made many bad choices throughout his career (3). In fact, an entire documentary has been made about the negative reception he has gotten by fans of his work. (4)
