I think you can expect to see a lot of that. When the X-Files had a lot of dark scenes it was edgy and contributed to the plot. The shadows became a character of their own.
Nowadays, I think shows just do it because with the advent of HD TV, the beautiful people don't want us peons to realize that they're not really all that beautiful.
I was given the first few seasons of “Smallville”. After viewing the episodes on one of the discs there will sometimes be a narrated episode or two with the directors or whatever they are called will comment as a voice over while showing the episode.
I noticed in one of those, one of the guys mentioned that Kristen Kreuk was one of the few actresses who could stand what they called “a slamma jamma closeup”. By that he meant that her face or only part of her face would fill the entire screen.
She is probably now 10-15 years older and her face will probably not stand a clear close up anymore.
