I read the article and while I agree than some people take things too seriously, harassing the actors in ways that are truly scary and are totally unacceptable, but everyone is subject to criticism about our work. We all have to answer to someone on how we perform, even having our own business. It's either having to hear criticism from bosses, customers or peers. Of course there are some people who can't be constructive or criticize without grounds, but if you can't take light criticism like the one she refers in her interview, I think you have a problem. Granted, it was a reunion but the comment wasn't mean, the person only said that they liked the first one movie better. Why get upset about that? Because our work can be very personal, we might take criticism on our performance personal, but we need to understand that many times it's necessary to get better at what we do. By the way, if you really want to enlighten some members or to open an interesting discussion, passive aggressiveness is not the way to go
EDIT: I think people get a bit more upset about movies being bad because it's a strange product that if you don't like it, there is no way to get your money back. So sometimes people feel conned and that the company is laughing on its way to the bank
