Given an English language product review, determine if it is a Good Review or a Bad Review. A good review is one where the product's review has positive tone and Bad review is one where the tone of product's review is negative.

Example Input: Although it looks like a nice little product, I could do without the loud motor noise that is emitted. The unit would work fine if you didn't need to listen for it. It also is not very loud. I did test the suction power though by using my hand vacuum cleaner with which I got good results. All in all, I'd say its worth $17 as long as you don't mind being aware of sound when vacuuming.
Example Output: Bad review

Example Input: I chose this rating because it does not have good suction power. It is easy to clean and handle. It's very light. My previous vacuum was the Hoover WindTunnel Animal Bagged Upright Vacuum, UH70210, which had better suction. Now I won't recommend it. This one isn't as powerful but you can't beat the price for getting a pet hair cleaner. The dust chamber seems to expand everytime i use it, so i'm looking for an accessory container that will make cleaning easier.
Example Output: Good Review

Example Input: Very disappointed in both this book and the seller I bought it from. Both were a used book. The cover was bent as if someone handled it. Some of pages had been torn away. It looked like they just threw my money down their garbage disposal. Do not waste your money. This author needs to come out with another book, preferably one that is from her new publisher. It's time for some real writing. One star because zero stars isn't an option.
Example Output:
Bad review
