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: there are three kinds of bad films - the cheap, the boring, and the tasteless. the only really bad movies are boring and tasteless. boring films are just, well, boring - if you don't leave quickly enough, you fall asleep.tasteless films actually have their defenders; but the fact remains that they are masturbatory aids for very sick people.only the cheap bad films are really funny, because the filmmakers wanted to make their films so desperately, they way-over-reached beyond their abilities and available resources.Bo Derek is just naturally boring and tasteless; fortunately, fate and a lack of funds and skill redeem her by making her seem cheap as well. this film is hilarious and it may well be the last really funny-bad film ever made.i first saw this in a theater, may god forgive me; i was laughing so hard i was rolling off my seat, and so too with most of the rest of the audience.it's clear that Derek and her husband-promoter, conceived of this film as, partly, a satire; unfortunately, the dereks clearly lacked any of the necessary resources to pull that off; consequently, the 'satirical' element comes off as some school-girl's impression of some gay young man's impression of frank gorshin's impression of the riddler in batman trying to pretend he's robin - it doesn't fly over our heads, it has no clue where any human head might be.on the other hand, there are some supposedly serious moments in this film - it is supposed to be an action film, remember - that are so astoundingly cheesy, one wonders if someone squirted spoiled milk in one's eye.as for Derek's infamous tendency to reveal her breasts - i can't imagine a less erotic nudity photographic display, she is so weird looking with those broad shoulders, i can't imagine what any one ever saw in her.as for the plot - such as it is - well, it isn't; Derek chases around Africa, and god alone knows why. then her father - Harris - pretends to act in some maniacal puppet-show, and then of course there's the hunk'o'Tarzan that seems to have wondered in from advertisement without knowing that the subject's changed - probably because he hasn't seen a script - apparently no one has.negligible camera work, shoddy editing - if it weren't for the 3-way with the chimp, the film would be unbearable -as it is, it's a real hoot. Question: is it a positive review?
Example Output: no

Example Input: Review: I really didn't like this movie because it didn't really bring across the messages and ideas L'Engle brought out in her novel. We had read the novel in our English class and i absolutely loved it, i'm afraid i can't say the same for the film. There were some serious differences between the novel and the adapted version and it just didn't do any credit to the imaginative genius that is Madeleine L'Engle! This is the reason i gave it such a poor rating. Don't see this movie if you are a big fan of L'Engle's texts because you will be sorely disappointed. However, if you are watching the movie for entertainment purposes (or educational as was my case) then it is an alright movie! Question: is it a negative review?
Example Output: yes

Example Input: Review: ba ba ba boring...... this is next to battlefield earth in science fiction slumberness. genie francis (aka general hospital's laura) has a small role as a reporter and that in itself should tell you that this movie must be bad.... there is ben kingsley (an academy award winning actor) in this stinker and a few others decent actors. You have to wonder what possessed them to decide to do this awful movie. The music dramatically goes up and down like it's a major dramatic story. Even if you pay attention the plot is impossible to follow. The effects are mediocre as well and seem really dated. All of the actors speak in a monotone voice and have no realism to their dialogue. I could go on and on on how this is a bad movie. At least with Battlefield Earth it's so bad it's funny but this is just b o r i n g. Avoid unless you want to be lulled to sleep. Question: is it a negative review?

yes
