All are good films - 1984 with John Hurt and Richard Burton is especially disturbing.
THX 1138 originally was the San Francisco phone number of George Lucas. He inserted that number into a few Star Wars films, plus it was the license plate of the yellow deuce coupe in American Graffiti.

It helped that, I believe, Richard Burton was dying when he filmed it and looked like the wrath of God.

THX 1138 was his most creative film with Star Wars being his most successful and 2nd most creative. From there on Lucas lost his mind, just more evidence that the cronyism of IP law has ruined those it was meant to protect.
