I think that she
(Kristen Stewart) probably meant this as an insult, or to degrade her profession (because you know, she's super teen angst-y like that). I think she's wrong. A movie or a play, like music, totally has the power to change peoples' lives. I mean, there are so many times that a movie has made me feel optimistic about life. Other times, a film can shake me to my core and have an extremely profound effect on me.
People use movies as an escape from their everyday realities.
So, yes, Kristen Stewart. Maybe what you're doing IS important.
