1. Felicity Smoak
It’s hard to believe that we ever made it to this stage because Felicity Smoak was once a breath of fresh air. A beloved, enjoyable addition to Arrow, she brought some much-needed levity to the show’s darker days, and Emily Bett Rickards was a delight in the role – so it was no surprise that Team Arrow’s reliable, lovable, tech-wiz became a series regular for season 2.
Unfortunately, the creative team failed to realize that you can, in fact, have too much of a good thing, so when Felicity graduated from supporting character to main character in season 3, the quality of the Arrowverse show significantly declined. Now Oliver’s love interest, the writers were forced to retcon the comic-accurate Oliver and Laurel romance that was clearly the show’s initial endgame, to force Felicity to the front of the show. When that happened, it became about Felicity, and only Felicity. And not even the great chemistry between Rickards and Stephen Amell was enough to save it.
The humor, heart, and overall fun that Felicity brought to the show had evaporated by season 4 and fans grew weary of her inconsistent writing. Within a year, Felicity managed to make the kidnapping of Oliver’s son all about her, ruined Barry and Iris’ wedding rehearsal by publicly arguing with Oliver because she didn’t want to get married, and then subsequently interrupted their wedding to announce that she actually wanted to marry Oliver at the same time.
With Felicity it was all about her. It was only about her. And as a result, one of the most enjoyable characters on the show became its worst aspect. Forget the Dark Archer, Felicity Smoak was Arrow’s biggest enemy.
