i think the argument is ideal prop vs. screen accurate. Just like collecting props, comparing to EFX collectibles legend series. Do people prefer an idealized parka (blue) for Han, what would be used in the SW universe or the screen accurate movie parka (brown). Whichever you choose, probably would put you in the legend or ideal prop collecting camp.
No need to debate, it's a question of which kind of collector are you? Screen accurate or story/universe kind of collector?
But keep in mind, if we were all collectors based on what the character or prop represents, then you really shouldn't complain if something is inaccurate or wrong shape/color. Like i said before, i'd like to see those people who prefer blue talk about how a figure is inaccurate. Think DX05 people!
) with a miniature model you see for about 10 seconds in total, never bigger than the Luke cutout you see next to the prop. And not because the miniature is less relevant itself, but because you simply can't tell the color of the parka from the stop-motion sequences (all during the snowstorm except for the first shot)...it could have been blue, brown, black, grey, any dark color. Nobody could have thought the parka was blue because of the miniature.
