I hate it when you have invested a lot of time in a TV show, following the complex plot and all the characters and then the show ends, leaving you hanging. Not knowing what happened next. How did the character’s lives pan out? There’s no more episodes, no more insight, just a hard, abrupt, end. As if you were a voyeur observing a life and then your window closed and there is no more for you. The character’s life continued without you knowing what happened next.
Some finish off their characters’ stories with leaked scripts post cancellation, or the stories continue in other media such as books or comics. Most end though, never to continue. Fan fiction satiates some, others, like me, are left with nothing. An investment with no end.
