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 only a response to the yahoo who says this movie is more realistic than the classic, genre defining MASTERPIECE, Jaws. Yes, brainiac, great whites(and other species of shark, bull, black-tip, oceanic white-tip, tiger)have been known to populate areas where easy prey is found. Humans don't often make it onto that menu, granted, but the shark in the film was repeatedly pointed out to be exhibiting abnormal behavior. It's not like it's never happened. The odds of a killer whale destroying nearly a whole town, singling out a human nemesis, sinking several dozen thick hulled North Atlantic fishing boats and knowing when certain people, all friends of the aforementioned "nemesis", are close enough to the water for it to reach, are so slim as to be laughable. Much like this turd of a Jaws knock-off. Laughable. Great white sharks are also known to frequently chew on boats, protective underwater cages and people on rafts and surfboards, as they look like seals from below. A shark the size of Bruce(if you don't know, look it up)would be more than capable of sinking a boat like The Orca(hey! that's the name of the blatant rip-off we're discussing!), as it would weigh upwards of 6,000 lbs. I could go on, but I don't need to. Jaws is amazing(better acting, better effects, better music, better writing), Orca is crap(BLATANT rip-off of Jaws, lousy writing, abominable effects, most ridiculous plot this side of an Olson Twins flick). It doesn't take a masters from Columbia University to see that. Watch better movies. Question: is it a negative review?
Example Output: yes

Example Input: Review: Not really spoilers in my opinion, but I wanted to cover myself, nevertheless. As the executive producer, Morgan Freeman wants the audience to ignore the numerous absurdities of his character in 10 Items Or Less, a movie with an intentional indie-feel, and just be absorbed in the mentor/be-all-that-you-can-be theme. He plays a alternate universe, semi-washed up version of the real Morgan Freeman, who is chauffeured in an old Econovan by a kid all the way into Carson, CA from Brentwood to research his next movie role. Why Carson, is a mystery to So. Cal residents. He could have saved the trip and gone anywhere in the San Fernando Valley and found the same elements. Paz Vega is pretty to watch, a cross between Salma Hayek and Penelope Cruz, playing a disgruntled grocery checker at a large but slow local market that apparently is the ultimate source for Moragn Freeman's research. His character is only known as "Him" to allude to how actors are regarded when encountered in real life by average people-"Psst, that's 'him,' etc. Unfortunately, I was too distracted that Him had all kinds of worldly wisdom and advice but had no reliable return back to his home in Brentwood, carried no cash or debit card, or had the wisdom to keep a cell phone with him. If one has such a high opinion of their self that they believe they possess an answer to everything like Him does, then I gotta see cash and a Blackberry which displays intelligence and good survival instincts to preserve that big ego which Him definitely has. Nothing really happens in this movie. I don't believe that either of the main character's were substantially changed by their encounter with each other. It flirts with the idea of adultery, but then that thought fizzles. This to me was similar to Steve Martin's Shopgirl, without the sexual affair. It was self-indulgent for Freeman and unconvincing to the audience. Question: is it a negative review?
Example Output: yes

Example Input: Review: The movie is basically a boring string of appalling cliches which do not offer a real cross-cultural insight. The Middle Eastern leg of the journey is described in a particularly irritating way: there obviously are mud brick villages, dirt tracks in the middle of the desert, women clad in black robes and belly dancers. I wonder how camels and date palm trees were missing from the whole picture. The personality of the two main characters is very clumsily sketched and many situations are hardly credible. The original idea might have been interesting, but at the end of the day if you are looking for cultural insight, you should skip this movie. Question: is it a positive review?
Example Output:
no
