Example Input: Interesting book. A bit too much for me, though. The authors spend an excessive amount of time talking about their philosophical views.
Example Output: Good Review

Example Input: Very happy with this set. The knives aren't that sharp, but are easy to sharpen. We would reccomend it for anyone who wants something cheap and very affordable.
Example Output: Good Review

Example Input: This was a great concept, I think. A quick read with all the usual fun of LeCarre novels. Unfortunately it is poorly written and very confusing. The characters, especially Paul Theroux, are caricatures -- they're not well defined at all in this story. There's no point to the story, just some people who come together for sex. Very disappointing after previous thrillers. I'm giving up on Mr. Rebus now - too boring
Example Output:
Bad review
