I don't really see those things as "charm" as such, I'm in favour of the best possible presentation of the series. When we're talking about effectively remaking the whole series from the rushes, some things will inevitably be different. The whole HD presentation is something that was never intended.
It's just a change in resolution, nothing else. It doesn't change anything about the composition of shots, the design of elements or the content of scenes. Rushes and improvisation and stock shots and mistakes are part of
any film production, plain and simple. TNG has
always been a show where they say "Distance to target five thousand kilometers" and then they show an external space shot where the ship is only 500 meters away. Picard says "Increase speed to warp 6" and Geordi says "Aye sir, full impulse." Should we re-dub this because it's an error or should we just keep it as it was because it has been part of the show for 25 years already?
