Example Output: Good Review

Example Input: This is my second MDR-V6's I've owned. The first lasted 6 years before the plastic cracked on one side. But I kept them outside in all weather so they didn't seem to matter too much either. So when I picked up this new pair, I just knew that if anything would do it, these would. They're very solidly built, and not at all flimsy like some of Sony's...perhaps there were a few bad ones, but mine came looking perfect unlike another person's review.
Example Output: Good Review

Example Input: the first time I watched this film, I was extremely disappointed.. so for about 2 years, every Halloween after that one and after, they still released this movie as if people thought nobody had bought it to see it. This is probably their lowest rated film of all time. It just doesn't do anything right. It makes zero sense, the dialogue is, at best, terrible, and there's an absolutely no plot, nothing even remotely interesting, it's a complete waste of time, you'll be wasting your money.
Example Output:
Bad review
