Example Input: I really liked this movie. The story was a little predictable but with time watching it had lots of suspense and surprises. It kept you guessing.
Example Output: Good Review

Example Input: My dog loves these so I buy them in bulk for her. But it is a rip-off to pay $6.45 at the pet store and $4.88 here. Not cool because it's cheaper on Amazon. Buy elsewhere if you can't find these... then you will have paid too much! It is almost as silly paying Amazon more than double price...when I can get 6 or 8 of her faves from the store. So disappointed. Will not order again. And don't forget...
Example Output: Bad review

Example Input: I bought this to run my ipod while cycling (something I'd only had experience with doing in ear headphones). It worked for two months and then died. No display would come on. You get what you pay for. Don't purchase it! You'll be disappointed. Also, it takes some finagling to make a connection, even when your ipod's volume is set at 100. For the money, I expected much better. There are many, many other options available that produce better output. I'm still searching.
Example Output:
Bad review
