Last March, Amell announced he was ready to “move on” from the series. “I’ve always been a fan of television shows that, not only don’t overstay their welcome, but end in a manner that really packs a punch,” he explained. He said another “large part” of the decision was the fact that he is a father and a husband now. “A lot of my life and interests don’t really reside in Vancouver anymore,” Amell added, referring to where the series is filmed.
