10. Was The Five Even Significant?
As the Originals had to be written out to make way for their spin-off, the fourth season introduced The Five; in fact, the showrunners spent a lot of time establishing the brotherhood of the five, which suggested that the band of vampire hunters are important to the broader narrative of the show.
Connor, especially, was depicted as a major antagonist and a threat to the vampire population in Mystic Falls only to be killed by Elena who was a newborn vampire, which is very weird. Plus, the entire arc around the brotherhood eventually only concerned itself with Silas which felt wasteful.
