If merlin destroys the darkness somehow, Zelena will still be a villain (or if she changed it wouldn't be because the darkness was destroyed). There can always be a new villainous possibility. Many shows end with there still being "evil" to fight. So, when the heroes face the large threat, the series (book or tv) ends but they do allude to countless adventures continuing on.

Like Charmed, they defeated evil, but there would still be demons and etc to face in the future, but the series still ended.

Technically any show can go on forever, but then it becomes a little obsessive. They have to grow up and then it becomes as if we are living throughout their lives. We don't need to see Regina, Snow, and Emma etc to grow old and die just for the series to end because there will still be villains before and after them.
