Modern day audiences often ask themselves could Lucas have done worse than the star wars prequels or Indiana Jones IV. They clearly have never seen the Star Wars holiday special or Howard the Duck.
The Holiday Special was way worse than the Phantom Menace and Jar Jars antics, the original actors stumbled around in the tv special saying cringe worthy dialogue and mostly looking either bored, drunk or stoned out of their minds.
Imagine star wars episodes 7-9 with Mark, Carrie and Harrison. With poop and fart jokes and over the top rediculously bad cgi, and wooden and throwaway characters and moments and dialogue that makes you want to vomit.
