Story Arcs
There’s a couple of TV shows that were good but didn’t make my list because they contained story arcs. These are stories that encompass the entire season. Bad guy shows up in the first episode, and then he’s defeated in the season finale. Or, in the case of other series, the arc continues as long as the series lasts (The X files) or resolves at the end of the run (Babylon 5).
These don’t hold up well for me over time. Great in the first run, but not when I come back to it. Much harder for me to get into. The problem is that they need to be watched in order in entirety to get the story, and I need to see the entire season. Worse, if the story arc doesn’t work, it isn’t an episode or two that’s affected–it’s the entire season (Buffy the Vampire Slayer’s 6th season). One of the B5’s DVDs was not available so I was sent the next DVD, which created a lot of confusion for me because I didn’t know what was going on. I couldn’t just tune into an episode at random.
I’ve also seen the same thing in some books. There was a urban fantasy writer I picked up because I liked the title. There were whole sections that referenced the previous part of the series in a vague sort of way, and it essential to understanding what was going on. But I hadn’t read the first book, so I couldn’t get into the story. I never took the time to read the author again. On the other hand, I’ve picked up books with underlying story arcs that are less dominant–Jim Butcher–with a stong story that has a resolution. Those are written so that a reader could pick it up at any point in the series, read the book, enjoy the story, and maybe want to get the first book to start reading the entire series.
On the other end of the spectrum, there are also both TV series and books where they ignore what’s happening in previous books. One of my bottom five TV shows, Voyage to the Bottom of the Sea, was like that. The crew would encounter an alien or a monster trying to take over the world and act like it was the first time it would happened. Whereas, in shows like NCIS, they bring a character back who appeared in one episode in another season, and everyone knows her from that. Not necessary for us to have seen the episode, but it might make us want to see the episode.
A good story arc in a series should allow us to pick up at any point along the way and not require readers or viewers to have prior knowledge.
