Well, from the stand point that I tell them to Vote 0, the reason I say such things is to spark their interest. They see the 'vote 0' and think that I am playfully dogging my movie. They then have to investigate to make sure it is really worth a 0. After watching them, they might come to really like it and vote a 5, or they realize I was right and vote a zero, completeing the cycle. Either way, I get what I want and don't feel down when my movie gets voted off because I have a safeguard that I told everyone to vote it off.
