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: We've been served - a terrible film.Okay, I'll admit that since I'm white and have had no practical experience in the "competitive world of step-dancing," I might not exactly be an authority on this type of film. On the other hand, I do know a bad motion picture when I see it.And, boy, have I just seen it.Filmed in Low-Budget-Vision and directed by Ian Iqubal Rashid, ("A Touch of Pink"), "How She Move" tells the tale of how important it is to follow one's dreams - even if those dreams include bopping around to loud, irritating hip-hop music and speaking dialogue the average person would not understand if he or she had an international translator.I'll try to give a small synopsis of the "plot." First of all there are two actors that look like LL Cool J who work in an auto shop in Toronto (the Mecca of racial diversity), but still have time to practice dancing for eight hours a day. There are a few other guys in this "crew," including a token white dude and a guy that looks like Denzel Washington in "Malcolm X." There are also two women in the movie - one resembles Serena Williams and the other looks like Geraldine from the old "Flip Wilson Show." One of these ladies was kicked out of a private college because her parents spent all of her tuition on a drug-addicted sibling. The other girl, a member of Salt N Pepa, no doubt, is just plain no good.There's another guy who looks like Eddie Murphy's Buckwheat, while still another actor who's a Huggy Bear knock-off. These guys are rival step dancers. Evidently, this activity is very hard-core in the 'hood, and they are all practicing for the big "Step Monster" jam in Detroit.Since I was unable to understand 90 percent of the dialogue (perhaps some subtitles would have been useful, as in a Bergman film or that one music video by Snow), it's hard to explain what happens, other than there's a lot of arguing, the Serena Williams girl (who never smiles, by the way) becomes a freelance stepper (moving from group to group), there's some step-dancing and a lot of irritating hip-hop music.It's a typical rags-to-riches story; sort of like "Rocky" with a really bad soundtrack, "Rudy" with annoying rap music in the background, "Cry Freedom" without the laughs. But why does a film - which could have made a big impact on black audiences - have to contain drug addiction, bad parents and a title that sounds like a first-grader saying the phrase, "How she moves"?I was "moved" by this movie, however. Moved to leave the theater as quickly as possible. Question: is it a positive review?
Example Output: no

Example Input: Review: This is a truly abysmal 'LOCK STOCK' clone with a stellar cast and a terrible script. I have no idea why so many top British actors signed up to this junk, they must have been bribed. A miss match of a storyline goes on forever and ever and ever and if I hadn't have paid good money for it I'd have turned it off after 10 minutes. Not the worst film ive ever seen, that honour goes to the truly pathetic used bogroll of a 'movie' (I use the term loosely) 'GUMMO' (I feel like suing that so called 'director' for the lost hour and a half of my life) but this trash is nearly right down there with it. Definitely one of the worst 5 films I have ever seen. Stuff like this reminds Hollywood that they don't have a monopoly on truly awful films. Question: is it a negative review?
Example Output: yes

Example Input: Review: I'm sorry but this is just awful. I have told people about this film and some of the bad acting that is in it and they almost don't believe me. There is nothing wrong with the idea, modern day Japanese troops get pulled back in time to the days of Busido warriors and with their modern weapons are a match for almost everything. When the troops first realise something strange is happening does every single person in the back of the transport need to say "Hey my watch has stopped"? Imagine lines like that being repeated 15+ times before they say anything else and you have the movie's lack of greatness in a nutshell. Question: is it a positive review?
Example Output:
no
