Input: Consider Input: Bought this for my 5 year old Justice Leaguer. My son is not a rough player but we went through 4 (YES, FOUR) of them before we finally got one where the elevator didn't break in the 1st 2 weeks. Mattel needs to get their act together and design toys that have durability. VERY disappointing!

Output: Negative

Input: Consider Input: This book in the beginning was so slow that I finished a book twice it's length before I finished the first chapter of Tess of the D'Urdubervilles.

Output: Negative

Input: Consider Input: I'm thinking of cancelling my subscription. Ever since Time Warner Publishing acquired Essence, it seems to be cantering to dark-skinned white women and NOT Black women.
Output: Negative
