Given reviews from Amazon, classify those review based on their content into two classes: Negative or 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: Adapter worked flawlessly for six months, then became intermittent. Seems to be broken or shorted somewhere near the connector to the computer. Even the ridiculously flimsy cord from Apple lasted longer than six months, so I can't say I'm pleased. Macally says they'll sell the connector cable separately for $17.00 which is not much of a bargain.
Example Output: Negative

Example Input: can not believe I watched the whole movie, I kept hoping it could get better. Never did get any better, only worse
