I think that's a great analogy. But two questions come to mind:
1. Are there any movies that are not terrible for people who know enough to compare them to reality? Gell-Mann amnesia comes to mind. Most productions focus on telling a story and will happily ignore constraints of the setting if that allows for more dramatic scenes.
2. What about trans people playing cis people? Maybe they would be better suited for the role because of spending more time as their preferred gender, but otherwise the argument feels pretty transphobic if you simply switch cis and trans.
It's almost as if when you're an atheist and people who believe in god say that you're a believer or that you had a bad experience with religion etc. No, it is simply an indifference.
