What makes suspension of disbelief work in the most implausible of stories
How many times have you complained with something along the lines of, "How did Character A survive that gaping chest wound, or get from Point A to Point B so fast, or figure out the mystery with no clues?" And how many times have you gotten the response, "You're expecting realism from a book/show/movie with dragons/time travel/vampires?" Clearly, that's too easy a comeback. It can be used to dismiss virtually any complaint about a work, and yet you somehow have to answer it. Why are you okay with a story about time-traveling vampire dragons -- my idea, don't steal it! -- but bothered by relatively minor elements in the story? The answer is that rather than coming from a desire to nitpick the story to death, our reaction is natural, and it's no big deal if we have multiple types of 'realism' in our fiction.
