I prefer my comic book heroes to be bright and vibrant. I don't like this new subdued lighting system that makes colors darker.
To be honest I don't think that screenshot is all that representative of the changes. I don't know why there's a huge light source in one image and not the other, but I didn't really see anything like that when we were checking out costume changes on TC. Mostly all that I could tell being different were the specular maps being more differentiated based on texture (like metal being shinier compared to cloth or leather).
