Example Output: Positive

Example Input: The old saying hollywood never lost money underestimating the intelligence of the american people really hits you in the groin with this head shaker of a release.While the orignal classic rollerball hasn't even gotten an anamorphic dvd release, let alone a blu-ray!
Example Output: Negative

Example Input: I bought this product for my old Dell Dimension XPS-T450 to extend its usefulness. As I was unaware of that the maximum RAM for each slot was 256MB, the computer read as 256MB instead of 512MB. With the seller's outstanding assistance I successfully installed two replaced 256MB memories to get total 512MB, the system is now working fine and steadily. It is worth spending $28 to keep the old computer working as an experimental machine.
Example Output:
Positive
