It's been a decade since American Horror Story debuted with its first season, now called Murder House, and since then the series has seen multiple seasons follow it — the series begins its tenth season, Double Feature, next week — as well as spinoffs, including American Horror Stories, which just ended its first season. Dylan McDermott, who playedDr. Ben Harmon in the very first season of American Horror Story, made an appearance in the Stories season finale and now, the actor is looking back at having played the iconic character for a decade and how Ben has evolved — or hasn't.
