Depending on the tone of the review, and if I knew the reviewer, or had sent the book to them myself, I'd probably respond like the author did to you, just to say thank you for the time you spent. I wouldn't expect you to reply though. In my Meet the Book Blogger interview series, a lot of the bloggers say they think it's common courtesy for an author to acknowledge a review, so that would be my sole reason for responding, not to make the reviewer feel bad for not liking my book, and definitely never to yell at them.

If it's a really negative review, I don't know them, or I didn't send the book requesting a review, I typically just let those go and figure it wasn't their cup of tea. No big deal.
