You know they added ropes around Han's feet in '97? *rolls eyes* It was a pretty silly situation in '83 but I guess they didn't have this 'rope' technology back then.
And as for the celebration scenes there has been discussion on the sudden uprising of the citizens on Coruscant and the significant population of Cloud City (didn't they flee?) which was also under control of the Empire (there wouldn't be much celebration if that was the case) but what about Tatooine?
Again it's been discussed that the planet is under control of the Hutts far from the reach of the Empire, why do they care? My problem is if I lived on a desert planet with two freakin' suns why would I be out partying in the middle of the street?
I liked when Mos Eisley was an under-populated backwater town reminiscent of a Sergio Leone western.
