Why is Arrowverse and the story of Oliver Queen to end, so that other series can begin and the Arrowverse itself can enter a new age.

When Arrow first aired in the fall of 2012, its showrunners had a loose The Flash, started along with Arrow season 2. By the time season 5 started, Arrow was the centerpiece of the most ambitious shared universe in television history and there was no way to move forward with the original plan for the series' conclusion - ending it as it opened, with the shipwrecked Oliver Queen's escape from the island of Lian Yu.

Circumstances have changed over the past two years, however, and Arrow is no longer the critical and commercial darling it once was. The Flash is now the highest rated series on CW and the rest of the shows making up the Arrowverse - Black Lightning.

Beyond the larger multiverse that Arrow created, the story of the show and its main hero are all but played out after seven seasons. Stephen Amell, who plays Oliver Queen, said in an interview on Michael Rosenbaum's podcast, foretold futures of the Arrowverse.
