Priya Koothrappali – The Big Bang Theory
Aarti Mann showed up in The Big Bang Theory to play Raj’s younger sister. Many fans regard her as the fourth season’s main antagonist. Since her first appearance on the show, she was a corporate lawyer, the fans have despised her. Part of it stems from the way she cheated on Leonard. The breakup occurred in the fifth season’s seventh episode. She and Penny, of course, did not get along!
Cousin Oliver – The Brady Bunch
Robbie Rist played Cousin Oliver on The Brady Bunch. However, people disliked the character so much that it developed into a trope called” Cousin Oliver Syndrome.” This term refers to a young character introduced to an old show and needs to shake things up. Unfortunately, many people believe that typecasting only degrades shows. Oliver acted as if he were a human disaster magnet. He caused a slew of issues and threw the series off balance. Today agrees that Cousin Oliver “killed” the series. Oof.
