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: Vertigo co-stars Stewart (in his last turn as a romantic lead) and Novak elevate this, Stewart's other "Christmas movie," movie to above mid-level entertainment. The chemistry between the two stars makes for a fairly moving experience and further revelation can be gleaned from the movie if witchcraft is seen as a metaphor for the private pain that hampers many people's relationships. All in all, a nice diversion with legendary stars, 7/10. Question: is it a positive review?
Example Output: yes

Example Input: Review: This is by far one of my favorite of the American Pie Spin offs mainly because in most of the others the main character (one of the young Stiflers) always seems unrealistic in nature. For example AP: The Naked Mile. You have a teenage guy surrounded by naked college chicks , and has one in particular hot on his trail to rid him of his virginity "problem" and he ends up stopping mid-deed and rides a horse back to sleep with his girlfriend, who keep in mind gave him a "guilt free pass" for the weekend. I can appreciate the romantic aspect of the whole thing but let's be realistic; most people who are watching these movies aren't particularly searching for a romantic story.Whereas the most recent installment finally seems to realize who the audience is and good old Erik Stifler seems to wake up and smell the roses and as always Mr. Levenstein lends his "perfectly natural" eyebrow humor to the equation and scored a touchdown with this new movie. Question: is it a positive review?
Example Output: yes

Example Input: Review: Remembering the dirty particulars of this insidiously vapid "movie" is akin to digging into your chest cavity with a rusty, salted spoon. Perhaps "Home Alone 2: Lost in New York" (1992) was a bit on the predictable side, but this pathetic excuse for a film is just one of the most shameless bids at commercialization I have ever heard of. A boy fighting off spies/terrorists when he's home alone in a Chicago suburb with the chickenpox? Ridiculous! Why did this film have to be made? I am the kind of person who believes even terrible movies are not wastes of time, but rather learning experiences. However, this is actually a waste of time. It should be avoided at all costs. Question: is it a positive review?
Example Output:
no
