I personally would say that the droid assembly line sequence in AOTC is the worst sequence ever to appear on screen in a Star Wars film. It’s long, bland, inconsequential, and ultimately completely forgettable. Do you agree? What would you say is the worst? The Ewok movies don’t count, the Clone Wars animated movie or TV shows don’t count, the Holiday Special doesn’t count, and Rebels doesn’t count. We’re only counting the live action films: episodes I-VIII and R1.
I’d also throw the whole colosseum sequence in as a runner-up
