Writer Greg Rucka has penned an opinion piece for Hollywood Reporter, a high profile venue, arguing that the PG-13 on Man of Steel goes too far.  "[I]f you make a Superman movie you can't take kids to, you’ve done something wrong," he said.  While admitting he hasn’t seen the movie and doesn’t know why the film got the more adult PG-13 rating, he says, "[T]hat PG-13 on Man of Steel is making me nervous."

In his eloquent piece, Rucka expresses his concern that by trying to make Superman more real, it will lose the essence of the character, which is the idea of an immensely powerful being who chooses to "be selfless rather than self-serving."

"Words like 'realism' and 'dark' and ‘gritty’ get bandied about Hollywood as if the only merit a story can have is in its verisimilitude, but that’s a lie," Rucka wrote.  "Emotional honesty transcends reality; it's what allows disbelief to be suspended, and yet what makes a story stay true."
