While some “The Big Bang Theory” fans find Raj Koothrappali to be whiny and inconsistently written, Kunal Nayyar is able to focus on the positives of the astrophysicist. In an interview with HeyUGuys, he explained how much he enjoyed Raj’s growth over the years. Though he’s the only single character at the end of the series, he has come a long way. He can speak to women without being intoxicated and even secures Sarah Michelle Gellar as his date for the Nobel Prize ceremony.
“It’s nice as an actor to be able to evolve with your character,” Nayyar said. “If the show is the same eight years ago, nine years ago as it is today, then people would be bored. No one would be watching it. It happens to shows all the time, by the way, where a formula works, but then people outgrow the characters because they’re like, ‘No one wants to see people who have aged ten years still behave like they were ten years ago emotionally.'”
Raj may not get married and have children on “The Big Bang Theory,” but a favorite moment for Nayyar is when Howard and Bernadette Rostenkowski-Wolowitz (Melissa Rauch) name him the godfather of their baby, Halley. He doesn’t have a girlfriend, but he truly has a best friend in Howard.
