Nina Dobrev Doesn't Want 'Vampire Diaries' To Be 'Dragged Out'

'I think you can only tell a story so long until it gets watered down,' actor tells MTV News at TIFF about her CW series.

The fourth season of the "Vampire Diaries" is set to kick off in October, and from the looks of it, it might be the biggest season yet.

The upcoming season finds Elena (Nina Dobrev) transitioning into a vampire, whether she actually wants to or not.

And while that will make for one very compelling story line, Dobrev told MTV News that if the writing for the show doesn't hold up to those high standards, she doesn't want it to continue on just for the sake of continuing.

"I always like it when a show ends on a good note. I don't like anything to be dragged out past the point of quality 'cause I think you can only tell a story so long until it gets watered down," she explained at the Toronto International Film Festival. "And I think every show that I've enjoyed has made it to the sixth season and put a conclusion to it."

But, fans of the supernatural hit CW soap shouldn't worry: No expiration date stamped on it just yet. She added, "But, I don't know. We'll see. It all depends on the story."

Well, for now, fans can focus on not only Elena's transition, but also her choice to be with Stefan (Paul Wesley), after her brief fling with his bad-boy brother, Damon (played by her real-life boyfriend Ian Somerhalder).

"I understand why she made the decision," she told MTV News earlier this year. "I respect her decision, and I think, having seen the last three years, what's happened in her life, everyone will also. They may not be happy, half the people will not be happy regardless, but they'll get it, and it's her decision at the end of the day."
