I was watching a TV series based on a popular novel the other week, curious about how the showrunners were going to adapt it to the big screen. Turning a book into a movie or series can be a daunting task in the best of circumstances, even if you leave out the messy business of Hollywood. But in the case of this particular TV series, my curiosity was more focused on whether the show would lose steam two-thirds of the way through. That’s because I’d read the book it was based on, and I remember distinctly losing interest just past the midway point.
Much to my surprise, the TV series remained faithful to the book on a level that I’m sure would make most authors ecstatic. The problem is that the TV series fizzled two-thirds of the way through. And I knew exactly why: the protagonist got too comfortable.
