Input: Consider Input: It was painful to watch. I was tempted to give it two stars - I love his parents in this movie - until Sam and his girlfriend hopped into the company car after finding out her boss worked for the deceptions. It was just bad.

Output: Negative

Input: Consider Input: A classic story based on history. One of Hypatia's crimes appears to have been ready to provide a hypothesis of a heliocentric universe, long before Copernicus and with a much worse response from the Christian community.

Output: Positive

Input: Consider 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.
Output: Negative
