We don't have a lot of reviews on this site anymore, for a simple reason: my lack of time.
But I get offered stuff all the time to review, though. I just refuse it.
In the past, I would get physical books, movies, and CDs, send them out to site users to review, and then... that was the last I would ever hear from them. The thing was... everyone seemed to read, watch, and listen to the stuff without incident. It was the writing the review part that never happened. Once, someone said they watched the movie two months earlier, but didn't get around to writing the review yet. Not sure about you, but I don't know if I want to read a review of something written two months later.
The other oddness is that people often didn't review the piece, but went off on some tangent of what the book could have been, based on their expectations. Like, instead of reading what was on the page, they would think that this character was going to do something else, so they wrote that was what they expected, and then didn't like where it did go as much. Which, again, wasn't really a review of the work. I hated Iron Man 3, but were I to review it, I would say why I didn't like the actual film they made, not come up with a version I would have enjoyed more.
But now, I am getting requests for Oasis to review e-books, so I'm debating revisiting this policy of people volunteering to review things, since they are just sending a cheap file and not a finished book, I feel less on the hook if we don't follow through. ;-)
So, is anyone interested? It is going to be very limited at first, since I've been turning publishers down for a while.
