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: Darkly comic serendipity about a cosmetics saleswoman, with odd ties to Elvis Presley, running into a sea of Elvis impersonators while speaking at conventions in Nevada...and accidentally killing each one of them through little fault of her own. Kim Basinger, a still-attractive actress of considerable merit, likes to pick quirky movies to play in, but this dreadful screenplay (by Mitchell Ganem and Adam-Michael Garber) hasn't an iota of good humor. The stereotypes and low-ball gags are not meant to be the stuff of classic comedy, but even on a shambling, shameful level, the picture is crude and sloppy. If you do watch, see if you can count how much extraneous shots there are of Basinger behind the wheel of her pink Cadillac, hands always in the same position and a non-plussed look on her face. Hopefully both she and Elvis were well paid. NO STARS from **** Question: is it a positive review?
Example Output: no

Example Input: Review: I saw this movie about a week ago and still keep thinking about it. I was very moved by this movie. I found the characters very believable and likable almost to a fault. As in real life though sometimes people disappoint, as was the case with Leo, who even though I liked his character I could not have been more disappointed when he was willing to have unprotected sex even though fully aware of his HIV status. I was also disappointed with Leo for rejecting the medicine available to him, and the awful way he treated Marcel when he decided to ship him back home on the train. I think this movie showed in a very real way why HIV numbers are up in young gay men. This is in no way meant to bash gays (I am gay) and movie very well could have been made about a young straight person who makes bad choices and seems unaware of the consequences to himself and others. The only part of the movie I couldn't understand was why the (gay friendly) family was unwilling to include Marcel in Leo's illness to the point of not allowing him to go to the funeral.I think the biggest message from this movie is that whether gay or straight is DO NOT HAVE UNPROTECTED SEX!
