“It seems pretty clear that the book should never have been released (and that Lee was very likely manipulated into agreeing to release it) “
I see nothing wrong with releasing weaker works by writers whose works have passed the test of time.
It is interesting to see and provides a perspective for readers who respect the masterpieces.
I would agree that it oughtn’t have been released a couple years after. But after 50, in a fully understood context, it’s of value and interest.
As a general rule, I agree, and perhaps my post was worded a bit too strongly. But, Go Set a Watchman reads very much like a rough first draft (which is pretty much what it is). Between that and the likelihood of some manipulation of Lee by her lawyer and others (which raises the significant question of whether Lee herself truly wanted to release it), I'm not convinced that it should have been released, at least as it's own work.
