I am a huge fan of science fiction and fantasy, and have been reading these books for 20 years. I picked up the Foundation books because Asimov was supposed to be so great, and I really enjoyed his short stories. This book - all of the books in this series - is so amazingly boring it could be used to replace Thorazine. The concept was solid, but the characters made me not care at all. I kept hoping they would die simply so there would be something interesting happening. If you must read it, check it out from the library and save your money. Unless of course you're a chronic insomniac; then, by all means, buy this book.

Ex Output:
Negative

My 6-year old and 5-year old both really enjoy this game. Has lots to do with several different animals to prepare for the parade. You get to design a float and it just endless fun! Graphics and animation are very colorful and cute. It's a winner!

Ex Output:
Positive


Ex Input:
Sometimes back to basics is the clearest path towards understanding current realities. It is amazing to me that a book written in 1946 is still so fundamentally relevant.

Ex Output:

Positive
