Thinking Laterally....
It's a better idea if any flipping of shots happens... Then the Reveal should be left in tact and the horizontal Executor travelling left to right and any other subsequent shots with errors should be flipped in preference of flipping the reveal in my opinion.
The empire arrives at Hoth travelling from Right to left so the executor and the fleet for continuity should mirror this and the reveal should be treated as correct and all other shots should be fixed in terms of lighting direction and improving the flow.
How about that idea as a better alternative?
Or do a lot of people just want to pick at the first shot because they want it to be a star destroyer?
