Example Input: Great product. Had bought it from PetCo originally, but they no longer carry it. So, I was very thrilled to find it online. It's exactly what we were looking for. A good sturdy tool that our Jack Russell puppy can handle easily.
Example Output: Good Review

Example Input: Works very well, easy to read even during day or night.
Example Output: Good Review

Example Input: The other reviews are pretty accurate with the story of how great this film is. It is a masterpiece. In fact, if I could, I would give it 4 stars. The problem is, you can't get the Blu-ray transfer anywhere. You have to wait for Netflix to put up its own release in September which will include subtitles. This should be remedied right away. I've asked amazon, and they refuse to provide one. My advice? Stay away from all streaming media until it's available on BD (or blu).
Example Output:
Bad review
