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: This is a very good movie. Do you want to know the real reasons why so many here are knocking this movie? I will tell you. In this movie, you have a black criminal who outwits a white professor. A black cop who tells the white professor he is wrong for defending the black criminal and the black cop turns out to be right, thus. making the white professor look stupid. It always comes down to race. This is an excellent movie. Pay no attention to the racist. If you can get over that there are characters who are played by blacks in this movie who outsmart the white characters, then you shouldn't have any problems enjoying this movie. I recommended everyone to go see this movie. Question: is it a negative review?
Example Output: no

Example Input: Review: Alas, poor Hamlet. I knew him, dear reader, and let me tell thee, THIS VERSION SUCKS! I don't know who of all people put up the money for this flotsam, but I hope that they're proud of themselves. They took THE classic play and turned it into the most boring melodrama imaginable. This version is quite literally so bad, that not even the presence of a great thespian like Maximilian Schell in the title role can save it. This movie's only redeeming quality is that it made great fodder for "MST3K"; Mike, Servo and Crow had a lot of fun with this one.But either way, I'm sure that Shakespeare, had he been alive when they made this, would not have wanted his name associated with it. This "Hamlet" is not even so bad that's it good; it's just plain bad. Absolutely dreadful. Question: is it a positive review?
Example Output: no

Example Input: Review: Though not seen in too many films prior, you have certainly seen the basic plot themes in too many films since. Not one of Grant's nor Loy's best films, they make an outstanding effort together. After all, with that much talent and very good supporting cast, you know the laughs will be there.The film is light, has some dramatic spotting but keeps the plot moving and gets you to smile the whole way through.A great example of classic American film fare that has stood the test of time.Definite Saturday afternoon fare, heavy on the popcorn. Question: is it a positive review?
Example Output:
yes
