11 most disliked Arrowverse characters, ranked

3. Cecile Horton

I feel really bad putting Cecile on this list because she was one of my favorite recurring characters throughout the first four seasons of The Flash. In fact, the idea to make her a secret weapon in the war against The Thinker was inspired. However, the second half of the show’s run, fans have grown weary of Cecile’s repetitive storylines, invasive observations and, quite frankly, corny writing.

By the time the show concluded with its ninth and final season, she had less depth than ever, with her desire to be a fun-loving superhero overwhelming any potential in her storylines. She’s not a serious character, which is frustrating because she was more serious when she was featured in a recurring capacity.

Cecile was at her best when she has more grounded storylines, and Danielle Nicolet was an always-enjoyable part of the show. Unfortunately, the writers stopped caring about what Cecile would actually do in situations and turned her into a cartoonish-over-the-top character destined for little more than goofy storylines and a supporting role in the infuriatingly repetitive Chester and Allegra subplots.

She was a lot of fun when she was written right. But that hasn’t happened in a very long time, and fans regularly cite the mishandling of the character whenever talking about the weaker aspects of The Flash.
