Input: Consider Input: This video is fine for ballroom dancers, but it has nothing to do with the authentic Argentine Tango. Even ballroom dancing has now a separate category for Argentine Tango. Unfortunately, this video is not that. That's why, I rate it at 1.

Output: Negative

Input: Consider Input: This is the definitive watershed work that brought Buddhism to the West and explains it in a manner that's very easy for Westerners to understand. It is a wonderful book that uses a question and answer structure like the Catholic Catechism to enlighten the reader on the Buddhist faith. It covers every aspect of Buddhism and there's much to learn from it whether you are a beginner or a master or from the East or the West. I strongly recommend this book. I got so much out of it. This book answers a lot of very important questions, including ones that I have had for some time. It's been a real blessing to me.

Output: Positive

Input: Consider Input: Bad acting and a cheap love story make this one of the worst Transformers movie to date. I wish the Transformers movies would focus more on the actual transformers of the movie instead of a bad love story. I remember Transformers the animated movie was all about the transformers and didn't try to focus too much on the humans and their problems. The fight with Megatron was epic and Unicron was an amazing villain. And the rivalry between Skyscream and Megatron made for an interesting plots on the decepticon side. The exploration and fights on the distant planets was fun and exciting. My suggestion to make this movie great instead of bad or mediocre is to fire all the bad actors and do a movie strictly about the transformers and their backgrounds. Or simply remake the animated movie into an actual motion picture.
Output: Negative
