Example Input: This was a good introduction but, for some reason, it wasn't as riveting at the beginning and got boring towards the middle. A lot of the characters were not developed to any depth in terms of description which I thought took away from that part alot. Other sections seemed rushed, too many events happening within one day. But on a whole, it's an interesting read if you have little knowledge or interest in what happened before 9/11.
Example Output: Good Review

Example Input: Excellent video quality. It is nice to be able to leave my laptop in charging dock while watching tv from bed.
Example Output: Good Review

Example Input: This item worked fine when we first got it. It doesn't hold a charge more than 15 minutes now and I am having to constantly remove it from the laptop in order for it not to keep dropping out of charge. Total waste.
Example Output:
Bad review
