Input: Consider Input: Review: One of the most timely and engrossing documentaries, you'll ever watch. While the story takes place in the Venezuelan capital of Caracas, it provides an intimate look into political dynamics, that prevail throughout the western Hemisphere. While essentially another chapter in the story of the "U.S. backed, Latin American coup", this film chronicles in real-time, what can happen when the poorest people, are armed with unity, political savvy, and courage! The political insights offered by this film are invaluable. One gets clear examples of the private media, as a formidable force for mass deception and propaganda. We see the poor people of Caracas grappling with the brutal realities of "American politics". One gets a clear sense of impending doom, if the people fail to address the blatant tyranny, which has been abruptly, and illegally, thrust upon them by the conspirators. We also see the arrogance and fascism, of the CIA backed, private media, plutocrats, and generals, who've conspired to bring Venezuela back under Washington's domination. Though ably led by President Hugo Chavez, the people of Caracas are forced to act without him, after Chavez was forcibly kidnapped by renegade generals. Their response is the highpoint of the film. If one seeks an excellent portrait of what the U.S. government, Hugo Chavez, and revolutionary Venezuela, are all about, this movie is it! Question: is it a negative review?

Output: no


Input: Consider Input: Review: I enjoyed this movie,and after watching it,it made me wonder just how many 'Caitlin Rose's' exist in the world.How many other girls have been subjected to this sort of sexual abuse,and torment by classmates and have been too frightened to open their mouth about it? Just how threatening and cruel can teenagers be towards one another,because as this film demonstrates,who's right is not foremost important,its who is popular,and feared which manipulates the minds of youths,and influences them to allow this sort of immorality to happen.Tiffani Amber Thiessen gives a powerful performance as the rape victim,and Brian Austin Green is convincing as the guy torn between the girl he thought he loved,and his best friend.This is the kind of film that doesn't get the exposure it deserves.Remarkable,and brilliant,too good to be just a film made for TV. Question: is it a positive review?

Output: yes


Input: Consider Input: Review: Dr. McCoy and Mr. Spock find themselves trapped in a planet's past Ice Age, while Capt. Kirk is in the same planet's colonial period. However, it's the former pair that has the most trying time. Besides the freezing temperatures and sanctuary to be found only in caves, there is a third inhabitant, the beautiful and so sexy Zarabeth (Mariette Hartley). As Spock spends more time in this era, he slowly begins to revert to the behavioral patterns of his ancestors, feeling a natural attraction to Zarabeth and throwing "caution to the wind" about ever leaving this place. Only with Dr. McCoy's constant "reminders" does Spock hold on to some grasp of reality.This stand as one of the few times when the character gets to show some "emotion" and Nimoy (Spock) plays it to the hilt, coming close to knocking the bejesus out of Deforest Kelly (McCoy). Surprising to previous installment, Captain Kirk (William Shatner) wasn't allowed to get the girl, another plus for this one.Perennial "old man" Ian Wolfe assays the role of "Mr. Atoz," the librarian responsible for sending the trio into the past. Question: is it a negative review?


Output: no
