It's part of the "dark movie" sickness that really got started with the Batman films, I think. You've got all these directors that think, "Wow, what if I make everything really dark, dank, rainy, ugly, depraved, depressing, overcast, and horrible! Won't that just be soooooo scary. Ooooo-Wee!"

Then they all keep imitating each other and it just goes on and on and on...movie after movie...

Tedious, tedious.
