I'll second that notion that the closer things are to reality, the more we demand them to be real.
My argument lies with the progression video games. In an age long past, we used funny little icons to represent our character and the actions which he performs. It didn't matter that it was a little yellow circle eating pills and dodging ghosts. Yet, we never questioned the logic by which his world worked.
But now that we have fancy realistic graphics we start applying real world logic to it. You now find yourself questioning why am I trying to find these presents? Why is my character jumping that high... why are things not dying when I shoot them. We are now confused unless things follow the logic that exists in the real world.
Science fiction is like the first one... we can't understand it. After the first few lines of technobable and fictional theorems of quantum fusionisious space travel our brain realizes that it is not the real world. We stop judging things based on real world logic. Without these firm logics, we can easily suspend our disbelief.
