Creating a TV show is no easy feat.
There's a lot of work that goes into it, from the conception of the programme to the running of the show, all the way down to catering. It seems that creating a series at times can feel like juggling multiple key components, which is why things often get dropped.
As a TV show shapes and moulds itself, it creates plots and narratives that carry it forward. Typically, these end up being explorations of characters, worlds and storyline potential that gets paid off later down the line.
But, that isn't always the case, as there have been many times where something is set up only to fizzle out, have a weak pay-off or get abandoned entirely.
Getting invested in a plotline that ultimately goes nowhere is one of the most aggravating things a viewer can go through, as it feels like a complete waste of time. The question always arises, "if you weren't going somewhere with it, then why include it at all?". This has happened so many times, and it never gets easier to sit through.

10. Gotham - Harvey Dent, Not Two-face
Introducing an iconic villain who audiences are familiar with in their pre-evil stage was Gotham's bread and butter. The series inherently sought to bring the origin stories of Batman's rogues gallery to life, which is what made it so disappointing when Harvey Dent arrived on the scene, only to disappear off the face of the Earth - pun intended.
As soon as the assistant district attorney of Gotham City appeared in the show's first season, fans were eager to see his dramatic descent into becoming the villain Two-Face. They patiently waited for the time to come but never received it, as after being useless in helping Gordon get out of jail in season two, he was never mentioned again.
The showrunner - John Stephens - claimed that this decision was made because Harvey Dent didn't become Two-Face until after Batman arrived on the scene. However, Gotham was a show that took a lot of liberties with the Batman mythos, so this excuse rings rather hollow.
Whatever the reason, there's no denying that the introduction of this character was a pointless side venture that brought very little to the show.
