Example Input: My son absolutely loved his new phone.
Example Output: Good Review

Example Input: A good book of this kind always has a few moments when you may wonder "what is the point?" This book certainly had those moments, but that's really to be expected. All in all, some interesting thoughts, as well as some very real examples presented with compelling prose. The downside for me was that it often didn't seem like Mr. Gladwell's point at all. Most often, what he wanted us to think about was either not a problem or just wasn't worth worrying about.
Example Output: Bad review

Example Input: The product is what he needed to combat foot fungus. It really works.
Example Output:
Good Review
