CBS hasn’t had tremendous luck with its higher-profile summer shows, Under the Dome bleeding viewers and critics alike with each year, and at last the dome will be coming down in more ways than one. The network has confirmed the September 10 finale will be the show’s last, cancelling the Stephen King adaptation after three seasons.

CBS boss Nina Tassler had chummed the waters a bit in revealing at the TCA press tour that the dome would come down by Season 3's end, though only now has the network confirmed an official series finale. Only days before the finale’s end, CBS has released a new promo and statement on the matter:

Two years ago, Under the Dome broke new ground in the summer and became an instant hit on CBS, as well as with viewers around the world. Dome’s event storytelling and multi-platform business model paved the way for more original summer programming with the successful rollouts of Extant and Zoo. We’re excited to present the final chapter in Chester’s Mill as the story comes full circle, with the Dome coming down as dramatically as it went up.

Worth noting is that Under the Dome was originally envisioned for a single-season limited series, before initial success spurred CBS to pad things out additional years. Unclear, is if the cancellation of Under the Dome will boost the odds on the likewise critically-derided Extant, or Zoo.

Under the Dome has seen better days, but did the Stephen King series deserve another shot next summer?
