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 must give How She Move a near-perfect rating because the content is truly great. As a previous reviewer commented, I have no idea how this film has found itself in IMDBs bottom 100 list! That's absolutely ridiculous! Other films--particular those that share the dance theme--can't hold a candle to this one in terms of its combination of top-notch, believable acting, and amazing dance routines.From start to finish the underlying story (this is not just about winning a competition) is very easy to delve into, and surprisingly realistic. None of the main characters in this are 2-dimensional by any means and, by the end of the film, it's very easy to feel emotionally invested in them. (And, even if you're not the crying type, you might get a little weepy-eyed before the credits roll.) I definitely recommend this film to dance-lovers and, even more so, to those who can appreciate a poignant and well-acted storyline. How She Move isn't perfect of course (what film is?), but it's definitely a cut above movies that use pretty faces to hide a half-baked plot and/or characters who lack substance. The actors and settings in this film make for a very realistic ride that is equally enthralling thanks to the amazing talent of the dancers! Question: is it a positive review?
Example Output: yes

Example Input: Review: Some gorehound-friends recommended "Live Feed" to me, and basically I can't really complain as the film certainly does deliver copious amounts of gross smut and buckets full of sleaze, but it is of course not a very good film. More than obviously cashing in on the latest trend in horror cinema, the so-called Torture Porn, Ryan Nicholson tries to surpass every other film in this sub genre (and that includes the role models "Hostel" and "Saw") with its sick & twisted make-up effects and thoroughly depraved shots of naked co-eds tried up, suffering and begging for their lives. There's no actual plot to describe. Five utterly brainless twenty-something friends take a trip to Asia. One of them has Asian roots, but other than that I don't really know why they opted to travel there instead of to Cancun. They're clearly not interested in the continents culture and even cause a hectic scene when they witness a local butchering a cute puppy dog on the market. The quintet subsequently dives into the lurid night life and one of them accidentally insults the leader of a criminal clan. A simply apology clearly doesn't suffice, as the gangster follow them into an adult theater and gradually subject all of them to vicious torture. One girl has her breast impaled and another poor wench even has a poisonous snake shoved down her throat; yikes. "Live Feed" is surprisingly boring despite of all the bloodshed and the amateurish production values are quite difficult to overlook, even if you're used to watching independent fan-boy trash cinema like this. The fat bloke depicted on the cover, an oriental S&M executioner, is admittedly quite cool and he's also the most talented of the whole bunch, because he at least keeps his mouth shut the entire time. I wouldn't exactly recommend this pile of filth, but hey, if you like loud & hideous metal music, nauseating torture footage and dim-witted losers, go right ahead and watch!
