The "Under the Dome" season finale saw one explanation of what the dome is all about, with the aliens claiming the dome is not to punish the people of the town, but to protect them. Executive producer Brian K. Vaughn spoke to The Hollywood Reporter on Sept. 17 about his show and its future.
When it came to the fact that the critical buzz died off as the series progressed, Vaughn said that was alright because the only audience member he wanted to make happy was Stephen King. Vaughn then said that King has been thrilled with the show.
When it comes to things that worked in season one and things that didn't seem to work out, Vaughn said that part of the journey in making a television show is seeing what works and adapting in future seasons.
As for that future, Vaughn said that what has Stephen King so excited is about what happens in the future. The book only lasted a few weeks and King wants to see what happens in this town when these people are trapped for a longer period of time.
Vaughn also said that the answer to who is behind the dome will be very different than that of the Stephen King novel. Whereas in the novel, the aliens who put down the dome had malicious reasons, the season one finale of "Under the Dome" shows they might have a very different reason.
