But you need a story in your head to make you care enough to vote or decide. Otherwise this is just those random fictional fights polls which are "hey here are two hot girls pics I found who wins" When you are familiar with celebrity and their work you have formed an image mentally of how you imagine they would be in a fight scenario. You also can imagine WHY they might be fighting certain people. With two unknowns you don't even know if they have even met.
A successful poll needs a draw, a story to it even if unspoken.
