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: We purchased this series on DVD because of all of the glowing reviews we had seen here. I gave it three stars because there can be little doubt that sometimes the acting, directing and writing are brilliant. In fact they are so brilliant we did not see the propaganda that was being transmitted so smoothly on the series. If one watches it with discernment, one will see the entire litany of the radical right wing beliefs being promulgated by the Fox (Faux) News Network. To avoid giving away any spoilers I will refrain from pointing out all of the dozens of specific instances. A brief look at the plots found here on IMDb will disclose that everything from torture to gun control to the right of a network to provide "Infomercials" and call them news is justified with cute plot twists and impassioned speeches given by some of the best actors in the world. We watched many shows and finally gave up in disgust when they justified torture using Attorney General Gonzales as a shining example of why all kinds of torture should be used in the name of protecting all of us. The series also manages to demean male and female gays in subtle ways by using them as plot devices depicting evil people. All in all the complete litany of the radical religious right wing.No doubt the popularity of this program will be used by future historians as proof that America lost its way in the early part of the this century. As a student of history myself I would characterize this program as being in a league with the propaganda produced by Goebbels for Hitler and some of the propaganda produced by Hollywood for the American audience during WWII.So if you want to use this as a teaching tool to help your students understand how subtle propaganda can be then by all means do so. Just be sure to purchase an inexpensive used copy so you can avoid enriching the ultra right wingers at Faux Network who produced this travesty. Question: is it a negative review?
Example Output: yes

Example Input: Review: This is one of those films that I could only sit through once. Charlotte Henry is fine -- in fact, all the actors were fine. The problem was in the script, the dialog, the direction, the editing, the sets and the special effects. Granted, this was 1933, but it really creaked. Part of the problem is that actors like Richard Arlen, Gary Cooper, W.C. Fields and Cary Grant are not recognizable (there faces cried for a recognition that was not forthcoming). The movie just clumped along with no cohesion. Much of Lewis Carrols spirit, humor and continuity are missing. What a pity! It's such a great book. I would recommend Disney's 1951 version. Question: is it a negative review?
Example Output: yes

Example Input: Review: This film seems to be well remembered as the time Tom & Jerry signed a peace treaty. Things are idyllic for a time but, predictably, it goes sour. Probably the most memorable moment was the endless fight involving a pipe, a frying pan, and a baseball bat that the two plus Butch the dog engage in at the beginning and end of the short. I enjoyed one a bunch and you should try to catch it on Cartoon Network. Question: is it a negative review?
Example Output:
no
