When books get adapted for screen or television, it’s almost certain there’s a clear and definitive end, at least if it’s not a book series being adapted. If you read the book prior to the adaptation, you get to decide if the movie or show is a worthy interpretation of its original source material. Or if you haven’t read the book before watching the adaptation, it may convince you to read the book. I’ve always been convinced a standalone novel that becomes a movie or TV show would always be enjoyed as a self-contained story, a one-time piece of entertainment to consume and re-watch whenever you feel like revisiting it. Instead, when a show or limited series becomes a massive hit, albeit a bit controversial, studios are quick to renew it for another season. That’s the end result of Netflix’s original series 13 Reasons Why.
