Assessing books - or any other creative media - in anything other than the context of the time they were written is pretty daft, let's face it.

However I do remember the books and I agree that they were competent, but not brilliant, writing... so it's not like they're "cancelling literary classics".

I also don't think there's anything hugely wrong with copyright holders altering older stories to make them more suitable for a modern audience, to be honest. Not when it's just pulpy adventure stories. Obviously we don't want revisionism of actual classics. They should however come along with education about historical context when read by teens (which of course, they usually are, and that's usually half the point of studying them).
