Aaron and Eric - The Walking Dead
Most viewers forgot they were even a couple because of the complete lack of attraction between the two characters.
Sydney and McKay - Euphoria
Euphoria is one of the most controversial shows around, but one of the couples are just not interesting. Sydney works much better on her own, away from McKay. The latter is too overbearing.
Evan and Stephanie - Ambitions
Evan and Stephanie are married. They're also two of the most powerful people in Atlanta, but they can't help but think about sleeping with other people. They're together just to keep up appearances, and nothing else.
Ian and Trevor - Shameless
Trevor was thrown into the mix as a placeholder for Mickey. As a result, his relationship with Ian was not built on a strong foundation and that's why they were one of the worst couples.
Clarke and Finn - The 100
Finn was Clarke's romantic interest during the early days of The 100 ... until she sacrificed him to make an alliance with the Grounders. His death gave fans a huge sigh of relief.
Archie and Veronica - Riverdale
Archie and Veronica have been set up as an endgame couple since Riverdale's inception, but the big issue is that they don't work well together. They're not an exciting pairing.
