There are many books out there, which retell a story (usually a classic or a really popular one) in a modernized version or by another character's perspective and I believe that many people in this forum have read such books.
In my opinion, though I've never read such books, I think that it is really silly and just an easy way to make money. Why, for instance, would I want to read Pride & Prejudice from Darcy's point of view, when I have created a personal picture of his character, or even Lydia's, presenting her better than she was? Cause she wasn't supposed to be.
I believe that if you aren't inspired enough to write something of your own, better not write at all. What is your opinion?
