Now on the one hand, that means the movie is far from dead... great news, right? Sorry... no. On the other hand I don't think it exactly spills rays of sunshine on the project.
Why do I say that? Let's have a look at the collective resumes of David Goyer (who is out) and Shawn Levy (who is in)...
The Good: Wrote the screenplays for Dark City, Blade and Batman Begins.
The Bad: Wrote the screenplays for Blade II and Blade: Trinity. Directed Blade: Trinity.
The Good: Um, ok... let's see... directed Cheaper by the Dozen? (Best I could do. That's not really good for this movie, but at least I liked that Steve Martin flick.)
The Bad: Directed Cheaper by the Dozen, The Pink Panther (YIKES!) and Night at the Museum. Overall almost nothing but comedies, and as if in confirmation:
Sources said that Levy, who before "Museum" had been known for such comedies as "Cheaper by the Dozen" and "The Pink Panther," has no intention of making "Flash" a comedy but is aiming for a lighter movie than previous Warners comic book adaptations, such as "Batman Begins" and "Superman Returns.
As I wrote here, I do think that as a character The Flash needs a lighter treatment than Batman, but lighter than Superman? If someone other than a comedy director was at the helm, I might not be as worried. What's really wierd (disturbing?) is that Goyer supposedly wrote a darker script, which the studio didn't like yet they're using elements from it for the new story. Scary.
