Well, I like noise. That is, I like it better than silence. When I start riffing in my head faster than the riffers who have presumably had time to write and rehearse their material, I get so mad I want to mail an angry letter demanding my 99 cents back.
With some movies, covering up expository dialog might be a problem, but the plot in this chapter is exactly the same as the in the previous 5: Bad guys kidnap somnambulant princess, scary magician tries to rescue her, evil minions get in his way, vapid upperclass relatives dither, repeat. The details are unimportant and uninteresting. And as Rabbit Ears says, the combination of low production values, a potpourri of dialects, and the ravages of time have made listening to the dialog, if not impossible, more trouble than its worth.
