Glow was cancelled by Netflix after three seasons because of the COVID-19 pandemic, but there’s a lot more to it than that. Originally, the show was actually renewed for a fourth season, but a lot went down in the past couple of months.
Vulture is explaining that to keep a huge cast like Glow safe with new safety protocols, Netflix did not believe that they would be able to return to production until 2022. Netflix then worried that by 2022, fans wouldn’t be as invested in the show and the cost to return to production may not be worth the product.
The article also states that COVID-19 safety protocols are very costly for productions. We’re hoping no more TV shows are casualties to this mindset and things can resume safely soon!
