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 tells the tender tale of a demented scientist who, after his fiance is decapitated, goes around ogling strippers so that he can find a suitable body to attach her noggin to. Everyone in this movie exudes more slime than a snail, particularly our protagonist. Question: is it a positive review?
Example Output: no

Example Input: Review: Predictable, told a thousand times story with the usual drama in between, a couple of pretty raunchy sex scenes intermingled with some character paranoia, 70's style incidental violin horror music that is comical at times, i couldn't help chuckling to myself.I usually like Defoe, and it has to be said that the acting is not all that bad, the "plot" develops at a reasonable pace and does keep you guessing from time to time. Its just that it's all too predictable, i felt like i was watching a made for TV drama instead of a new movie. Maybe thats the style the directors wanted, but it has to be said that the review i read on here before i saw the movie could only have been written by someone involved in its production.Don't expect too much, and if i could wind the clock back i wouldn't have gone to see it at the cinema. I would wait for the bargain bins at your video shop, I'm sure it wont take long. Question: is it a negative review?
Example Output: yes

Example Input: Review: This was a watershed event in my movie watching life. I went to see this in the theater when it came out. I was completely amazed at just how bad it was. Movies like this make you wonder who put the money up and who owed whom a favor - a very, very large favor. The special effects are absolutely first grade level, as in any first grader could have done them. Toy rubber bats on strings with no attempt to hide the strings, arrows that appear to be drawn on the film and look to be the shape of an arrow you'd find on a street sign, and a laughable story line. Ed Wood made masterpieces compared to "Conquest". Every film student should see this thing just so they'll know the very definition of a bad movie. Question: is it a positive review?
Example Output:
no
