Agree that there are limits, especially when it comes to rewriting and not just transplanting a work to another era.
I liked the Peter Sellars'"Marriage of Figaro" set in Trump Tower, for example, because the music and libretto stayed the same and the privileges of aristocrats in Mozart's day resembled those of the one-percenters today. But "retellings" of classics go too far for me when they change the meaning of a text rather than helping you see that meaning more clearly (which should be the point, in my view).
