Well, I think the traditions are here to stay but it's unlikely that they will be with the same scary treat they have always had. And I do highly doubt that given the media we have these days. If you have not watched a movie unveiling the mystery behind the story that has long been scaring you, then you must have read about it. Have you watched that horror movie or have you seen these people dressed up like the jokers.
Yes, the Halloween will survive but not for the reasons it had long been existent.
