As for the content, I thought it was good, unobjectionable reading, but nothing that jumped out as something that belonged in the Bible. To be fair, though, I don't always get impression from the canonical books either.
One thing that struck me as very strange: though they are said to be part of the Old Testament, the KJV Apocrypha follow the New Testament example of putting proper names in their Latin forms. I never understood it in the NT, and I don't get it here.
As far as I can tell, the Apocrypha isn't necessary, but not something to be afraid of, either. I'd recommend it as good reading, but get it in a version that's easier to understand.
