Superman Returns suit was one of the darkest time in Superman history.
Wish I had one of the suits so I could burn the God Damn Thing.
The suit isnt perfect by any means but it had a certain "real world" sense to it.
As much as a costume like Supermans can have anyway that has it's underwear on the outside.
That is to say, given the design parameters that everyone was familiar with (cape,briefs,"S" shield),
trying to keep that plus make it an alien material and not cheap spandex as well as tone down the garrish cartoon colors, they succeeded imo.
I wouldve made the boots taller, the "S" shield a tad bigger and put the the yellow "S"back on the cape.
Perhaps its the way it was filmed but the colors seem darker than the publicity shots.
The colors still look more than vibrant enough.
I really dont think the fans would be very happy with a Superman suit as Reeve wore in a modern cinema version of the man of steel.
It was almost all spandex!
Cavill will most likely wear a suit closer to the Returns version than the Reeves version soooo,.
Costume fabrication tech has come alooong waaay, it should be utilized to make our comic icons look as good as possible while respecting the historical designs.
