Example 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.
Example Output: Negative

Example Input: While this movie was not "highly acclaimed" when it was released, back in the late 1960's or early 70's "I think," I have always like it and watch it about once every two or three years. It is the kind of movie that you never get "fully bored with."On a scale of 1-5 stars, I give it only four (4) stars, since it is one of those movies that many "action junkies" would not like; even-though, it actually has quite a bit of "lower key action" and beautiful phototgraphy to support it.My bottom line is: "If you liked Dr. Zhivago then you will, or should, like Ryan's Daughter."
Example Output: Positive

Example Input: This novel was the most boring book I have ever read. I would never put another person through the torture of reading this long-winded dull attempt at a scandalous and exciting romance. Even though there is much symbolism to be found, when is one supposed to find it, while they are sleeping? Another factor of my displeasure with this book is that I love to read and now hesitate to pick up another Hawthorne piece. How did this book become a "CLASSIC"?
Example Output:
Negative
