I mean the issue is that often the "situation" they put them in is either super contrived or completely nonsensical, revealing that it wasn't just a part of the story but a deliberate shit on the parts of canon they don't like.

Like, you need to properly set such a thing up with justifiable in-universe reason if you are going to do it (which the "older, bitter Batman" angle did well enough), but so often the reason is entirely meta related instead.
