I will give you one more demonstration of how to stage this Argument or rather question for the OUT or atleast this would be my strategy of how to stage a question of why and why not.

Ben’s Hut.

The original has the boosters or engines missing Black holes are there where the art is missing. The very same composite is shown with R2-D2 and 3P0 with Luke and Ben by the sandcrawler with the engines or boosters present correctly.

Lucus at some point decided to use the side view alternate take which required no Compositing of engines.

When the Special edition appeared the new matte shot was based off the alternate side view but pulled way out to accomodate the new wide view of Ben’s Hut on the cliff.

Whilst I do not mind this change all that much should Lucus have just restored the engines of the Landspeeder completing the Special effects of the original shot?

This is how I would approach breaking down Lucus decisions on his Special edition and on this one we can see clear resons behind the change but is it the right choice?

that is the question that must be presented rather than an argument.
