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: After having seen the Canadian/Icelandic/British 2004 production of "Beowulf & Grendel," which I thought brilliant and stunning, I approached this--the first of 3 newer Beowulf movies due out this year--with trepidation. As soon as I heard "Viking" and saw the horned helmets, I groaned. These were Migration Era Swedes and Danes, not Vikings (they came later). And even the Vikings never wore horns on their helmets (horns make it easy for your enemy to knock your helmet off and then brain you). Then there's Hrolfgar's palace, which looks like a set for a movie about Greece or Rome, not 6th-century Denmark. The swords and armor look like props left over from earlier films set in various historic periods. I spotted weapons that might have been used by Crusaders in "Kingdom of Heaven," and one character was even wielding a Windlass Steelcrafts reproduction movie sword from "Beowulf & Grendel"! Beyond the basic plot of the original epic poem, the writing was dismal and the acting totally wooden and unconvincing. The biggest yuk was a secret-weapon crossbow, complete with sighting scope and exploding projectiles, that looked like something bought from Iraqi insurgents. The special-effects monster and his mom were so on steroids that Beowulf could never have torn off an arm, as he did in the poem. Thank the gods for bazooka crossbows! I could go on, but I won't. Question: is it a negative review?
Example Output: yes

Example Input: Review: i should qualify that title, now that i think about it. Checkout is not entirely worthless. i've had the opportunity to see it twice, and on the second time i did get a great laugh at the movie's expense. so i guess it's worth something for that. and also it's worthwhile for the excruciating pain it caused me on my first viewing. as another reviewer pointed out, this film is hackneyed in every sense of the word. not a single original thought went into this movie (which makes the comment below about the originality of the premise entirely baffling to me). the film is nothing but a long line of cliches which are strung together and paraded around as a movie. it is definitely not the next Clerks, it is definitely not original, and it is absolutely not "good, clean fun." the film is absolute agony to the uninitiated (after seeing it a first time, the second time can be quite funny, in an insulting sort of way). as i looked around the theater, it was obvious that nearly everyone, barring perhaps the elderly, were completely bored or pained by this movie. during some of the particularly emotional scenes, like where Nick chews out his mother, the audience was actually cringing because it was so poorly done. i even heard someone *groan* in the theater, something i had heretofore never witnessed. i don't care where you have the chance to see this movie, be it at a film festival, or in a indie theater, or wherever. do yourself a favor, skip this movie with a vengeance. unless you're like me and just can't resist the opportunity to see what may truly be the worst movie ever made. Question: is it a positive review?
Example Output: no

Example Input: Review: I saw this movie on a westbound American Airlines flight. It was so bad it actually made the flight seem longer. The plot had potential (who wouldn't love a movie about a woman who accidentally kills every Elvis impersonator she meets?) but it got screwed up a million different times by really poor writing. Towards the end is an embarrassingly bad scene where a gang of Elvis impersonators is on the roof of a casino reshipping the sky thinking he's going to return, then a group of stars moves together to form an "Elvis" constellation, which promptly shoots a bolt of lightning at the impersonators, sending them crashing through the roof. Bad...REALLY bad. Which is the theme for the whole movie. I'd avoid this one at all costs. Question: is it a positive review?

no
