"So when somehow high school shows become seven and eight seasons long, don't get me wrong I watch them all, but I tend to get a little suspicious of something that began as a high school show," Brian Yorkey says of ending his Netflix teen series after four seasons. "And it felt like bringing these characters to their graduation and to scattering to their next things felt like the logical ending point. So for a long time, the idea has been, should we be so lucky to have the opportunity, we would do four seasons of this. So certainly going into breaking story for season 4, we knew it was the end."
