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 movie kept me constantly entertained. In comparing this to Serial Mom, Mr. Waters has gone back to his grittier side. This is not nearly as polished.There is a dark side here. A message about how success and fame changes a person -- but more importantly how it changes the people around you.There is not a false moment in this film.The characters are somewhat cartoonish... but I want to believe that is what Mr. Waters is trying to achieve.It is fascinating to watch how Mr. Waters has evolved... This is truly his finest work. Question: is it a negative review?
Example Output: no

Example Input: Review: An axellent second installment that manages to be just as good as the first. Once again, the casting is just wonderful. I like how the first and second episode have nothing in common except for the wit and cleverness.The second episode is just very funny, very silly and very enjoyable. It is the very first Christmas episode, about a woman who is tormented by a serial killer dressed as Santa after having killed her own husband. Just like the first episode; karma.The most humorous scene is a tie between the murder of her husband and her phone call, first faking her fear until it becomes real. Question: is it a positive review?
Example Output: yes

Example Input: Review: One of the many vigilante epics that flooded the market by the mid-80s. The routine plot has echoes of "The Magnificent Seven" (believe it or not), the action scenes are lamely handled and the special effects are non-existent. You COULD do worse....but the film is still just a waste of time. (*1/2) Question: is it a negative review?
Example Output:
yes
