Input: Consider Input: Nice critic about inquisition times combined with a great introduction to small gods concept for those not familiar with it. Makes you think about faith while it makes you laugh about everything. If I had not read better Pratchett's books, I would have rated this with a five

Output: Positive

Input: Consider Input: Reasons not to buy this video:1. She reads from cue cards the entire time.2. She's extremely stiff and boring.I have only watched this video once in the two years that I have owned it.

Output: Negative

Input: Consider Input: I ordered this particular product as a trial substitute for the "Controlgel" by Textureline, which has always been my first choice. It appears that the "Controlgel" is out of production. This "Smoothing Serum" is a poor substitute. My barber agrees. He got me on the "Controlgel" years ago and I used to buy extra for him, but now, no more!! Too bad . . . we consumers lose again. I wish the "Controlgel" product would come back. My barber and I won't buy any more of the "Smoothing Serum." What a WASTE!!
Output: Negative
