Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: This is a highly entertaining show that you can watch over and over again. It deserves an Amazon.com double five star rating, it is that good. Think, if you will, of the Velvet One's rising to the top in spite of her talented and tabloid catching siblings and in spite of the emergence of girl groups who are flooding the airwaves and CD displays with soundalike claptrap which has only a catchy phrase or a man-slam to its merit. (Pay some dues, girls.) Look at the Velvet One's performance in the concert showstoppers--"Alright/I Get Lonely/Rope Burn" "Black Cat" "What About That" "Rhythm Nation"--I mean...is she great or what? And look at how many of the Velvet One's tunes you know by heart. There ain't that many performers out there of Janet's calibre at all these days...well, maybe a few of 'em. They seem to be calling themselves "diva". Oh well. Thanks, Velvet One, from saving us from an entertainment void.
A:
Positive
