Okay...but the point remains, in order to employ this argument, you are having to grant that, at least some of the time, entertainment value trumps fidelity, whatever thing that fidelity might relate to (physics, history, biology, whatever).
Ah, but now you have fallen into the exact trap I was warning you about: Why is this privileged but other things aren't?
You have to actually defend that. If you have granted "sometimes, entertainment value is more important than fidelity", you must defend why this case is special, why this thing requires the maximum fidelity possible, while other things don't. Or, more commonly, why an extensive list of exceptions to fidelity are okay, but a different extensive list of exceptions to fidelity are not okay, which is an even taller order than the previous!
