Example Output: Positive

Example Input: I purchased the Intex airbed to replace an Aerobed that our cats "loved" too much during a guest visit. Comfort wise, the Intex wins hands down-supportive yet comfortable as well. Convenience wise, it inflates a little slower than our old Aerobed (albeit, there is more to inflate) yet it takes up less room when rolled and stored in the sack that comes with it. The only reason I didn't give it 5 stars is because it is VERY high, so a restless sleeper can fall off pretty easily.
Example Output: Positive

Example Input: What can I say about this show except it is a good example of what a classic series is all about. Any John Ritter fan has to add this to their collection. I intend to purchase the entire series.
Example Output:
Positive
