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: I found Horrorvision almost unwatchable. While only 70 minutes in length I still found myself hitting the fast forward button again and again. The acting was of the `if I scream and say ***k a lot I'm intense' school. And the story was at best a scenario that had yet to be fleshed out.While I never go to Full Moon for great film making I have never seen them produce as bad a piece of junk as this. Question: is it a negative review?
Example Output: yes

Example Input: Review: I read nothing but good things about this movie and finally had a chance to watch it late last night and it was everything I expected it to be and more.This is the way a proper horror movie should be.I think the reason it was so scary was because it was so realistic. The spooky sounding score was perfect for setting a dark mood.I liked the dramatic opening scene and enjoyed how the rest of the movie played out.It was very easy to follow and understand unlike some movies which are way too complicated.The special effects were very good.I would love to see more horror movies like this one.This is easily one of my favorite's.A realistic thunder and lightning storm would have set a nice atmosphere for this movie.Other then that it had all the elements a good horror movie needs.I highly recommend this movie to anyone who can appreciate a good scary movie that pulls no punches.I will be adding it to my collection.The DVD has some interesting special features. Question: is it a positive review?
Example Output:
yes
