The creator labeled it as a ‘mistake’, as looking at his enthusiasm, he asked Fox to return for more episodes. Speaking with People Magazine, Lawrence said:“He made the mistake. He did the first [episode] of the year that's on in January, and he said, ‘That was so much fun. I'd do it again.’ And around me, if he ever says anything like that out loud, I'm like, ‘Oh then come back in two weeks.’ So he had to come back again.”Shrinking showrunner talks about Michael J.
