You can tell I've no interest - you lost me when you combined 'absolutely serious' and 'Star Wars' in the same post.If I can be absolutely serious for a minute:
Greedo shooting at all in that scene doesn't make sense and weaken's Solo's character and if it wasn't already abundantly clear by the point, Lucas had lost it and needed to have Star Wars taken out of his hands asap.
It was his "making Prince Phillip an Australian knight" or "Using a 2nd rounder on Matthew Westhoff" moment.
