Oh, don't know if I've ever posted this here, but I'm of the opinion that Christopher Priest has it in him to be one of the all time greats for a Superman book.
The fact that he's apparently never been invited to write anything Superman related is one of our great failing as species. Yes, he's effective with "dark" characters, but his rang in voices and characterizations are at the tip top in comics. Warren Ellis or Kieron Gillen are the only other two whom I can think of that in any way rival Priest in this regard. So typecasting him as *just* the guy that writes the f#&ked up dark characters is no an forever a fundamental misunderstanding of his strengths as a writer.
I'd absolutely love to see Priest get either a Black Label Superman book or the Batman/Superman book if it stars Luke and Jon, because unsurprisingly his seemingly infinite range in voices and characterizations lets him write some of the best young adult and teen characters around.
