I'm gonna just take a shortcut, and watch the movie, then make up my mind. Astroturfing or not, making up your own mind is part of the fun of being alive. Then "a genuine fan or a paid account" doesn't even matter anyway, because they're both as important when you make up your own mind.
Speaking about that, have you seen the movie yourself?
So the response to a deceptive promotional campaign should be, just get a ticket and see if what's promoted is good?
