Well, thing is: I tend to love the scifi bullshit. I eat it up, because in the good cases it is imaginative and mind-blowing and inspirational. It's the bad cases, though, where bad writing or bad writing decisions force an "Explain it away, Geordi"-type situation. It's in those situations where my attention level does me disservice.

Maybe the conclusion is: I dislike when writers decide when I should pay attention or not. Or, when they decide when I shouldn't listen. There's Treknobabble. And then there's being lazy.
