The Big Bang Theory's main couple, Leonard and Penny, had a happy ending that was predicted in season 1: they were expecting their first child. Despite some issues with the execution of the final arc, it was a feel-good ending that they deserved and harkened back to the show's earliest years. Leonard was committed to Penny from the start, even predicting that they would have smart and beautiful babies. While Penny's agency is undermined by the sudden excitement about being pregnant, the ending was generally well-received as it finally gave the Hofstadters a substantial life update after years of stagnation in the sitcom.
