complaints about “lighting” are silly IMO.
Even if no one goes to the cinema and choses the movie based on its lighting; cinema is a visual art which has internal codes that make it a language; and therefore it can be evaluated according to those parameters. So it’s not a silly complaint. It’s just pointing out a detail for those who valorate the importance of details.
Do you think it was casual that the previous shot of Vader saying I’m your father was a contrapiccato, conveying more power, and that the one where he says it is weighted to the left making it unbalanced? That the final celebration in ANH was shot mainly using centered perspectives with bright spots eclipsing the vanishing points, evoking order? Do you think the sensation at the opening of ANH would have been the same had the gigant ship flew below the camera (casting no shadow) instead of over it?
No, it’s not casual.
Check the latest interview with GL, he can clarify that a lot (I don’t agree with him however over the matter that visual storytelling hasn’t developed over the last century; I just think he didn’t look to European experiences enough).
