Another star exits Once Upon a Time, even as ABC has renews its fairy tale fantasy drama for a seventh season. Once Upon a Time has been a very successful series for ABC since its debut in 2011, and a natural one for the Disney-owned network to produce given that it has uniquely brought to life several classic fairy tale characters; including, Snow White, Prince Charming and the Evil Queen (though the show has also featured such modern favorites as Elsa and Anna from Frozen). But with viewership down this past season, the writing has been on the wall that changes would have to be made, if the series was to be brought back for another year.
