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: Saw this movie in an early preview, and I cannot stress enough how bad I thought this film was. From the very beginning, the audience was groaning over Pacino's awful southern accent. Poor Al looked really, really haggard, and I can't decide whether this was purposely part of his role as a drug addicted publicist, or perhaps he just didn't get any sleep before coming to the set. Much worse than Pacino's close ups, however, is the wretched excuse for a plot. Early in the film we are given indications that Pacino's character is gay, and I suspect that is what the screenwriter had originally intended. Later, however, we are supposed to suspend our incredulity and believe that both Tea Leoni and Kim Basinger (both of whom are sleepwalking through lame roles) lust after this elderly, half dead looking, effeminate man with the ridiculous accent. The worst part overall was the main plot thread, which had to do with some corporate espionage that is never fully explained and we never, ever care about in the slightest. Because this was a preview I will reserve my final judgment, because of the possibility of re-shoots and editing, but you can bet I will not pay a cent to see this in theaters. Question: is it a negative review?

Example Input: Review: Emory is a Cincinatti steel worker like his father before him and for most of the 20th century the twin pillars of his family's existence have been the steel mill and the union. The mill, which once employed 45,000, has seen its numbers dwindle to 5,000 recently and now 1, as the plant just shut its doors, leaving a single security guard. At first, newly-unemployed Emory and his pals enjoy their independence, hanging out around town and carousing at their favorite bar, where they down "depth charges" with reckless abandon. They think the mill will reopen after listening to their union rep's optimistic spiel, but reality starts to sink in when they find themselves selling their personal vehicles in a struggle to put food on the table and stave off foreclosure of their homes. Emory's father - a dedicated union man - is sure the plant will reopen and recalls for his son all the short-lived closures during his own 35 years at the mill. Meanwhile, some of the unemployed men take demeaning make-work jobs or hop in their trucks and take off in a desperate search for employment. Finally the union admits its helplessness, as Emory explains to his stubborn father that times have changed and that the mill won't ever open again. Emory tearfully asks "What did I do wrong?" as a lifetime of hard work and devotion to job, union, church and family have left him with nothing and nowhere to turn. He hits rock bottom when in a drunken rage he manhandles his young sons and knocks his wife to the floor. Tossed out of his own home and stinging from the plant manager's comments that he and his men didn't work hard enough to justify their substantial paychecks, Emory recruits the steel workers still left in town to do something that will demonstrate to all what they are capable of. Early in the morning they break into the mill, fire up the furnaces and work harder than they ever have in their lives, producing in one shift enough high-quality steel pipes to fill the loading docks from wall to wall, top to bottom - something the plant manager thought was impossible. Arriving at the suddenly-reopened plant, the stupefied manager looks around him at the tremendous output that came from a single day's work, realizing that production like this could make the plant profitable again. The manager asks Emory: "Can you do this every day?" Emory is forced to nod "No" and the manager asks: "Then what were you trying to prove?" Emory explains that the workers' decades of hard work, honesty and devotion to their jobs had meaning and that by showing how much they could produce in one day "We just spit in your eye." Emory bids a tearful farewell to his wife and kids as he takes off with his buddies to look for work down south, promising to relocate the family when he finds it. This is a powerful and honest treatment of the plight of American workers displaced by foreign competition and gives a realistic view of the costs they bear for the short-sightedness of concession-demanding unions and greedy plant owners who extracted every penny they could from their factories but never gave back by modernizing them. Peter Strauss as Emory, John Goodman as his best friend, Gary Cole as his college-boy brother, Pamela Reed as Emory's sympathetic wife and John Doucette as his dying father all turn in excellent performances in this fine picture.

Example Input: Review: UK newspaper reviews seem to have concentrated on the fact that the reviewers tend to know Toby Young, the journalist on whose real-life experiences this movie is based. The key word here is "based". How To Lose Friends is a fictitious romcom.Sidney Young joins a prestigious gossip magazine in New York, where he proceeds to make gaffe after gaffe before finally Getting It Right and Making It. This involves him selling out, and the movie has some serious points to make about journalistic integrity. However, they are not overdone: the main substance remains a comedy which centres around Sidney's misadventures. The script has its cake and eats it in that Sidney is a stupid, well-meaning buffoon at the same time as being a smart, moderately obnoxious skilled writer. This contradiction is never that much of an issue, because Simon Pegg (as Sidney) projects likability too well.Jeff Bridges underplays Sidney's editor a little too effectively, and Kirsten Dunst is rather anonymous as the conflicted eventual object of Sidney's affections And, with regard to Megan Fox (who plays an airhead bimbo starlet), I can say only this: just say the word, Miss Fox, and I will leave my wife, sell all my belongings, and buy myself a plane ticket in order to take my place at your side as your consort. Of course, given that I'm a fat 56-year-old English accountant, you might not find my offer too enticing, but it's there on the table anyway. Given how short her career has been so far, one might think it is a little too soon for Megan Fox to take on a role which mercilessly lampoons the sort of actress she might be thought to become: however, she does it sweetly, with some skill, and extremely sexily. This girl will go far.There is stalwart support from a variety of seasoned performers - Miriam Margolyes and Bill Paterson from the UK, Gillian Anderson and Danny Huston from the US.There are several laugh-out-loud moments, and I smiled most of the way through. As ever, the F-word makes appearances when it really doesn't need to, although at least a couple of these are very funny. Question: is it a positive review?

yes
