On Sunday, Matthew Weiner concluded the doom-obsessed penultimate season of Mad Men. On Monday, CBS debuted its new series Under the Dome, an adaptation of Stephen King’s epic novel about a lovable small town cut off from the outside world by a mysterious invisible dome.

They’re the subject of the latest episode of Entertainment Geekly, where we read the tea leaves on Dome‘s future and ponder the symbolic implications of Mad Men‘s past. And also argue about Man of Steel. Just kidding.
