If you really think about it, Chris Reeve's costume in STM may have looked more like what it did in the comics, but did not fit in with the design of the film itself. The costumes Jor-el wore on Krypton had high necklines and a small "S" symbol on both the reflective white one and the black one he wore when sentencing the phantom Zone criminals. In fact the red and blue blankets Kal-el was wrapped in seemed out of place! And if Superman's costume was made out of Kryptonian materials, why did it look like it was made out of spandex? Why was the S symbol large when Jor-el's was small? Why didn't it have a high neckline? It seems to me Singer is correcting the mistakes in costume design that STM had within the look of the film.
Remember, films are based on comic books, not a literate translation. Most literate translations would look ridiculous to the average moviegoer, who still considers superheroes as kid stuff.
