If you are a movie studio, a good way to tell that you've run out of ideas is if a headline in Hollywood Reporter looks in any way similar to this headline:
I was skeptical that a nine year old kid actually wrote what, from what I've seen, looks like a tongue-in-cheek parody of pickup books that at least had some assistance from an adult but, even if it's true, this is a self-help book and not a novel so what exactly will the movie plot be and GODDAMN, IT WAS WRITTEN BY A NINE YEAR OLD! They still haven't made Alfred Bester's The Demolished Man into a movie* and yet Fox is optioning dumb little books written by nine year olds? What, did he threaten to hold his breath till he turned blue unless you gave him a six figure deal and a share of the gross? You could have gotten a better deal if you told him that you'd release the monster you're keeping in the closet if he didn't sign away all rights to the book at that moment.
On the other hand, maybe I could cash in by writing a ripoff. Yeah, I could write my own book about how to pick up nine year olds...or maybe not.
*That's an awesome example of classic science fiction and it'd be well worth your time reading it.
