Zack Snyder has spoken candidly about his relationship with Superman. He told Entertainment Weekly: "I've followed Superman over the years. I wouldn't say I was a huge fan but I've kept an eye on the character in the pop culture, and as the pop culture has regarded him, for the past 10 years, especially."
Snyder is clearly not besotted with the character, which could position him as the right director to take a new look at the revered icon. He'll be entering the project as a filmmaker rather than a fanboy, and could use his unclouded judgment and filmmaking know-how to make decisions in the best interests of the movie (and the audience).
As he won't be carrying his own preconceptions, he should hopefully be open to Nolan and Goyer's apparently groundbreaking take on Krypton's favourite son.
