The great thing about such medium shifts is that it allows both the creators and the fans to experience the story’s world in a new way. For all the advances we have in technology, some feats are easier to accomplish on the page rather than on the screen.
There’s also the matter of money. Some shows are simply too expensive to keep going long enough for the narrative to wrap up, putting them on the chopping block. It’s often less expensive to switch the show to a different medium, such as a book, graphic novel/comic book, or a combination of both. I’d even love to see a story finished via video game. That may be a barrier for fans who don’t have the console the game is on, but it would still make for an interesting idea. With that Thrones show ending with a season of feature film-length episodes, it could set a precedent for reviving once-canceled/unfinished shows and giving them a proper wrap up without drawing things out too much.
The Story Won’t End in Tears...The Bad Kind
Touching back on behind-the-scenes shake-ups, what if a show you once loved doesn’t just jump the shark, but throws in a coupl'a backflips and twisting somersaults along the way? The show, book series, comic book series, or what have you ends alright, but it ends in tears of anger and regret. In this day and age, no matter how great something is, we have a tendency to focus more on what was done wrong or poorly. Sometimes, we even like to pretend that later, less-than-stellar seasons don’t exist, much like I do with True Blood.
It Can Come Back
Sometimes, the scope of a creator’s vision outpaces the technology available at that time. Rather than try to make do with lackluster visuals or look into shifting mediums, the creator may decide to leave the story unfinished...but not forgotten.
