Example Input: Umbra Coretto 24 to 36-Inch Decorative Tension Rod, BlackThe rod is really good looking. However, because it is so thin, the weight of my shower curtain keeps causing the rod to come loose. If I had any idea, I probably would not have bought the rod. However, my shower is at the wider end....so maybe a person would have better luck if their shower is closer to 24".
Example Output: Negative

Example Input: This book was interesting with great promise. The premise was fascinating but the writer fought with herself throughout. She spent a great deal of time on the flora and the fauna. There was always a paragraph on a bush when a sentence would do, a sentence on a tree when a word would suffice. The characters were well developed. Over all it was a good read.
Example Output: Negative

Example Input: I really liked the first one, and the second one was okay too. But Dark of the Moon was difficult to sit through for me. Endless dialogue with minimal action sequences, I found myself looking at the time far too often. They dropped Meghan Fox, who despite her controversial reputation, definitely added to the cast. The special effects are still amazing, but there just wasn't enough action. BORING!!! If they are going to continue with this franchise they had better turn it up a few notches.
