Steven Yeun, who played Glenn on The Walking Dead, has opened up about feeling frustrated with his character at times. He felt like he was servicing a concept of goodness rather than engaging with Glenn's humanity. However, Glenn's warm-hearted heroism was a crucial aspect of the show, as he served as the chief ally to lead character Rick Grimes and helped keep the show from getting too dreary. Glenn's brutal death scene marked a turning point for the show and impacted Rick, Daryl, and Maggie because of who he was, not just the circumstances of his death.
