You can't darken the colours of the world's greatest superhero!!!!!!!
He is a walking symbol of Truth and Justice (ok...and the american way- which in my opinion should be changed for us over the pond Superman fans). He has to be bright and visible, not dark and grimy like Bats. The primary colours of blue, yellow and red have are visually eye-catching and that is the whole damn point.
The tweaked photo of superman looks so much better than the final film product. A small 'S' for crying out-loud!!!!! And Singer clained to be inspired by Alex Ross...well mate that isn't how he draws it! Besides it just leaves a huge blue-void around the midriff. Plus a tucked in cape!!!! It looks like he put it on as an after-thought, it isn't anywhere near elegant or majestic enough! Total Rubbish!
To NOFATE007 - Ripped capes can look cool.
