Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: This book is so unrealistic that it spoils all the fun, super killers like Temple Gault (a clone for the Satan Incarnate known as Hannibal Lecter) are more silly than super. I found all the other character two dimensional and all the "intrigue" regarding super computers insulting to my intelligence. Has Cornwell done better? I don't know and, after reading this, am in no big hurry to find out.
Example Output: Negative

Example Input: We play a card game that requires holding several cards. These card holders are a huge help. I really like having multiple colors.
Example Output: Positive

Example Input: Check their web site at www.emarker.com. A pity. This looked like a good idea. :-(
Example Output:
Negative
