Rory Gilmore (Gilmore Girls)
To be fair, most of Gilmore Girls was actually great for their lead. It was actually the revival that didn't do right by Rory and it is hard to have that be the last image fans have of the character now.
Ginny Baker (Pitch)
Ginny Baker wasn't actually let down by Pitch, she was let down by the fact that the show didn't move on beyond one season. There was so much story still left to tell and the network failed a remarkable lead by not allowing that to be explored.
Rebekah Mikaelson (The Originals)
Rebekah moved from one show to another and somehow was always written into the same position. There was plenty that Rebekah had to give up throughout her story being told, and not enough was handed to her in return.
Allison Argent (Teen Wolf)
Does anything even need to be said? Allison wasn't the only lady that Teen Wolf let down, but her death still stings along with the memory that it left behind. This was a character that deserved so much better and the shame is how much of that was taken from her.
Jenny Fraser Murray (Outlander)
Sometimes it is like Jenny isn't given the benefit of the doubt, especially when it comes to the knowledge she possesses but the show almost sleeps on.
Lanie Parish (Castle)
There were so many stories Lanie could have been given during her time on Castle, and each one that wasn't followed through with came off like another lost opportunity. Lanie had so much to offer, so the fact that it wasn't utilized is still upsetting.
