Example Input: A delightfully funny story! A wonderful graphic novel that gives us a cat's-eye view of the Sephardic Jewish community in Algeria and then the Algerian community in Paris in the early 20th Century. It's a love story. Very funny and endearing. And the hero is a cat! This is a must for Joann Sfar fans.
Example Output: Positive

Example Input: This corkscrew is poorly made, consisting of low-grade stampings and flimsy plastic molded parts assembled with tinned rivets. It feels like it's going to come apart in your hand, and it requires considerable care to use it safely and effectively. It's outrageously overpriced, too. An unfortunate product offering from the company that brought us the legendary original Screwpull, perhaps the handiest corkscrew ever.I did manage to pull a cork with it, though - which is why it gets even two stars.
Example Output: Negative

Example Input: Hoover's choice of international financial manipulation as subject matter for this novel is timely and raised my expectations. Instead most of the story is pulpy romance surrounding a contrived conflict between Japanese investors scheming to revive Imperial Japan and American regulators intent on saving the free world. The only thing missing from this "B" grade movie plot are black and white hats to differentiate the bad guys from the good guys. Not at all what I had hoped for.
Example Output:
Negative
