In this task, you are given a review of a movie and a boolean question whether this review has positive sentiment or negative sentiment. Your task is to generate answer "yes" when the tweet has that particular sentiment, otherwise generate answer "no".

Example Input: Review: The third installment of the "Carnosaur" trilogy features a bunch of Keystone Kops-quality military commandos trying to kill two Velociraptors and a T-Rex. I give it a 4 out of sheer sympathy and my affinity for dinosaurs. The movie is definitely the worst of the trilogy, it really can't be taken seriously. More significantly, however, watching this movie I can't help but notice some interesting parallels between the "Carnosaur" and "Xtro" trilogies. The first installment in both franchises is a dark, disturbing film that has become a cult classic, the second is an "Alien" ripoff, and the third is a tongue-in-cheek, almost slapstick (whether intentional or not) movie that has you rolling on the floor laughing. Also, like the "Xtro" franchise, all the "Carnosaur" movies are completely unrelated to one another. They they only carry the franchise name to drum up interest in the "sequels," I guess. Obviously "Carnosaur" and "Xtro" have two different production groups at work here, but if you've seen all three movies of both franchises you find yourself referring back and forth between the two. Question: is it a negative review?
Example Output: yes

Example Input: Review: This movie is rated a classic on sentiment not on any quality of movie-making. It moves from the unlikely to the unbelievable, from the unrealistic to the ludicrous.The unbelievable plot revolves around an attempt by two British soldiers and a Hindu gofer to rescue a third soldier who has been captured by insurgent Indians. In the later scene we see a full regiment with drum and bagpipes marching into an ambush. In the British army, a sergeant does not order up a rescue attempt, and if you get past that, he does not attempt it with only one other soldier and an Indian servant when there is a full regiment on hand. The Indian insurgents are so incredibly inept it is laughable...there are hundreds of them but they can't hold their prisoner or kill the two rescuers, of course not. At one point we see the British soldiers throwing blocks of stone down from the battlements at the insurgents, who are scattered around the mountainside in ambush...one would have to have an eggplant for a brain to think this would do any damage. After Cary Grant as the rescued prisoner is shot, he lies on the floor looking around at the water boy...hardly the actions of someone who has been shot in the back. The water boy bravely blows a bugle (which comes from nowhere) to sound the alarm...this he does by standing up high on a wall so he can be seen and shot by the bad guys, and we shed a tear as he keeps trying to sound more notes as he is repeatedly shot and the bugle call breaks up into feeble squawks...instead of blowing the bugle while hiding behind cover as anybody with half a brain would do. This scene has deservedly been parodied in comedy sketches. If they wanted to make a Buster Keaton comedy, they should have hired Keaton and done it better. Question: is it a negative review?
Example Output: yes

Example Input: Review: This movie tells the tender tale of a demented scientist who, after his fiance is decapitated, goes around ogling strippers so that he can find a suitable body to attach her noggin to. Everyone in this movie exudes more slime than a snail, particularly our protagonist. Question: is it a positive review?

no
