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!

Ex Output:
Negative

Ex Input:
Vickery is certainly the best multi-dimensional male erotic fiction writer today. He is the Anne Rice of [homosexual] male porn.But even more, the humanity and spirituality of his characters [comes] through clearly - their pain, their joy, their search, their honesty, the lies, the hopes, the hot , out-of-control passion - everything else human. I was moved to tears, and compassion, and much, much more. Hot, hot, hot.

Ex Output:
Positive

Ex Input:
Looking for something to work with my Jawbone ICON. The set consists of 3 pairs of eargel (three sizes). Found the size that fit and inserted the ICON. Works OK, but not as snug as I would like on my right ear. Tried the left ear one and it was much better; fit was better and sound was louder. Tried several types of earphone adapters, and these seem to work better than most. If you have a problem with fit on one ear, try the other one.
