Yuuuup. On the technical side of filmmaking, Lucas is unquestionably the most important filmmaker of the last half decade - modern cinema is built on the innovations he and his team pioneered. But he's a shit writer and a mediocre director who absolutely requires mediation from others.
I used to sell appliances, and customer-brain insists everything they own is "only 3 years old."
Start digging and you find out they own shit that hasn't been produced in a decade or more.
