Question: I've bought this book, underlined every hint of symbolism, found all evidence of romanticism, followed every quote involving thematic oppositions, and noted every example of Pearl's rebellious nature and social alienation, but I cannot find one positive aspect of this novel that makes any of my hard work feel rewarding. The only way this novel could give me a warm feeling is if I place it in a furnace.

Answer: Negative

Question: I love how this product makes me look in my clothes!!! its shapes me into a perfect hourglass! i dont know if the claim that it permanantley reduces your waist after 30 days is true because i havent had it that long. my only complaints are that it is a little too short, so i still have a small bulge over the top in vthe back and i think it may be stretching out as i wear it as oppossed to it shrinking me, but overall, it is the best shapewear i have ever purchased. i love it and would recommend it to anyone.

Answer: Positive

Question: Usually I write a review only if I dislike something about a book. I rarely bother to write good reviews, because every book gets so many of them. In this case, however, I have to make an exception. For any fan of hard science fiction, "Pushing Ice" is AWESOME! It's got everything: realistic characters, solid physics and astronomy, believable near-future society (circa 2050), glimpses of far future society (circa 20,000 A.D.), some REALLY far future, aliens which are somewhat comprehensible, aliens which are completely beyond comprehension, rivalry, broken friendships, betrayal, marooning in space (on multiple levels), struggle for survival, etc. Even asteroid mining and that perennial "stranded in space" trick - using electric motors as generators :)

Answer:
Positive
