I disagree with the author's assertion that Smallville avoided suiting its Clark Kent up in his traditional primary colored spandex to preserve its realistic formula. The rationale the actors and showrunners always gave, which I agree with, was that Clark shouldn't wear the suit until he was officially Superman. Since Smallville was about how Clark Kent became Superman, it was obvious viewers shouldn't expect to see the suit until the show's final curtain call. Clark didn't wear the suit on Smallville because he wasn't Superman, in other words, not because the show was necessarily trying to be realistic and accessible. The formula they were following was more origin story than realism.
