The old saying hollywood never lost money underestimating the intelligence of the american people really hits you in the groin with this head shaker of a release.While the orignal classic rollerball hasn't even gotten an anamorphic dvd release, let alone a blu-ray!
Negative

I've been a longtime fan of Mercedes and own most of her Valdemar series. So, of course, I picked this book up at my local store. After wrestling through 50 pages, I gave up! I plan to sell it back to my local store ASAP- this is nothing better than a paperweight in my bookshelves. The worst part is, my boyfriend picked it up and tried reading it. Now he thinks that this is a good example of her work!

I love Dean Koontz. This was not my favorite. In fact I was rather unhappy with the whole book. Now don't get me wrong he is a great writer but this book bored me. I don't read to get bored.
