ReceptionEdit

The fourth season received particular praise for character developments. Alan Sepinwall of Uproxx praised the additions of Bernadette and Amy to the cast, writing that "With Amy Farrah Fowler and Bernadette promoted to semi-permanent status, the show is now able to spend large chunks of each episode focusing only on the women, and in the process has made Penny a much more well-rounded character rather than just a foil for the nerds".[26] Emily VanDerWerff of The A.V. Club wrote that "Jim Parsons and Kaley Cuoco's interplay remains the show's secret weapon",[27] and Eric Hochberger of TV Fanatic wrote: "Really though, everything about the main story worked amazing. Mayim fits in perfectly in The Big Bang Theory cast and played off of Kaley Cuoco just as well as Emmy Award-winning Parsons".[28]
