Myatt's quote is pretty terrible. It makes it sound as if we were forced to suffer through half a day of tedium in order to experience this big pay-off. First of all, nobody that was born prior to May 2005 even had the capability to sit through 12 hours of Star Wars for this big pay-off. I sat through six hours to get to Vader's redemption. I'm sure everyone else here did, too. So the quote is inaccurate.
But mostly it just diminishes the whole Saga. We don't just sit through it, we delve into it. We savor it. We go back to it over and over and over again. We watch the movies to watch the movies, not just to get to the end.
Dave must have been trying to sound clever, and it came off poorly.
