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: 'Cry Freedom' is a movie about how far people will go to find the truth.The first half is an interesting portrayal of an unlikely friendship between activist Steve Biko and Editor Don Woods (played fanatically by Dezel Washington and Kevin Klein). While the second half deals with Woods looking for answers on Biko's death.Although most people favor the first half of the movie which focuses on the unlikely friendship between Biko and Woods'. I found the second half about Don woods struggle to have Biko's story be heard around the world much more interesting. Question: is it a positive review?
Example Output: yes

Example Input: Review: Once again Jet Li brings his charismatic presence to the movie screen in the film Black Mask. In this film Li plays Tsui, an escapee from a super soldier program who seeks to regain the humanity that the program had taken away from him. To do this Tsui decides to become a librarian in order to live a normal and peaceful life, but fate demands that he clean up problems from his past before he can continue to seek peace. Other members of the super soldier program had escaped at the same time as Tsui, but they want to get even with the world rather than find inner peace. Thus Tsui becomes the only thing that can prevent his former team mates from releasing information that could cost many innocent people their lives. This film screams across the screen at a frantic pace and never lets its audience go. The martial arts is amazing, but because it uses wires it may not be appreciated as much as it deserves by American audiences. If you like action movies that have an interesting story and demand good acting performances because they deal with psychological as well as physical conflicts, then Black Mask is for you. I am glad to see that some of Jet Li's movies are finally getting main stream release in the United States and look forward to seeing how the changes that that release will require (things like dubbing and soundtrack) will affect the film. This is one of Li's best films, go out and see it on May 14 when it is released in America. Question: is it a negative review?
Example Output: no

Example Input: Review: Saw a trailer for this on another video, and decided to rent when it came out. Boy, was I disappointed! The story is extremely boring, the acting (aside from Christopher Walken) is bad, and I couldn't care less about the characters, aside from really wanting to see Nora's husband get thrashed. Christopher Walken's role is such a throw-away, what a tease! Question: is it a positive review?
Example Output:
no
