I just wrote a post on my blog about this, but thought I'd start a discussion here as well. The basic situation is this: Yesterday, I picked up a book I forgot I had already read. It felt familiar, and about halfway through, I went to goodreads to check it out, discovering that I had in fact *tried* to read it four months ago. I didn't finish, gave it one star, and a scathing review.
Yesterday, I did finish the book. I do agree with my earlier comments, but they didn't bug me as much this time, and overall I'd give it three stars. Perhaps not a night and day flip flop, but pretty significant for me, especially since I try to reserve my one-star reviews for books that truly deserve it.
Luckily, this particular review didn't make my blog, or I'd probably feel worse. I imagine I'll update my goodreads review with the honest truth, but I found myself wondering if anyone else out there has ever changed their mind about a book? What do you do if you reviewed it?
