Example Input: This was very disturbing reading. Nothing like the authors other novels so far. Not sure what she was thinking? Don't recommend at all.
Example Output: Bad review

Example Input: As other reviewers have noted, the only thing I can say for this DVD is that it's a shame so much excellent work wasn't released. The worst sound I've ever heard on any home video, not even by VHS. What sounds like some old radio plays was in fact re-recorded tracks. If you're interested in these films then check out theUltimate Collectionor theseWarner Brothers Movie Legends Collection. These are superior DVD's and don't look half bad either! Don't waste your money here.
Example Output: Bad review

Example Input: I was a little nervous when I ordered this after reading some reviews not the highest but it did what it said to do. The price wasn't too great either. It fit really well and for some reason my dog didn't seem bothered by it. Good product at a good price. Thanks amazon again! My pet peede in less than 4 days. Great product. Love it!
Example Output:
Good Review
