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: The Return is one of those movies for that niche group of people who like movies that bore and confuse them at the same time. Sarah Michelle Gellar plays a lame buisnesswoman who does not kill vampires or get naked at all throughout the movie. I was willing to put up with this, however I was not willing to put up with the worst editing ever combined with pointless flashbacks. At the end it turns out she crashes her car into herself when she was young. Or maybe I'm wrong and that was just a flashback. With this movie it's impossible to tell. Can you believe the same dude who made Army of Darkness produced this crap? A much better idea is to stay at home and watch Army of Darkness on Sci Fi channel. That movie had it all: sluts, zombies and a dude with a chainsaw for an arm. The Forgotten didn't even have one of these things. Question: is it a positive review?
Example Output: no

Example Input: Review: Intrigued by the synopsis (every gay video these days has a hunk on the cover; this is not necessarily to be construed as a good sign) I purchased BEN AND ARTHUR without knowing a thing about it. This is my second (and I assure you it will be my last) purchase of a CULTURE Q CONNECTION video. As far as I am concerned, this DVD is nothing but a blatant rip-off. I do not make this observation lightly I am a major collector of videos, gay and mainstream, and I can state with some authority and without hesitation that BEN AND ARTHUR is quite simply the worst film I have ever sat through in my life. Period. My collection boasts over 1,600 films (93% on them on DVD) and of those, well over 300 are gay and lesbian themed. I hardly own every gay movie ever made, but I am comfortable in stating that I pretty much purchase almost every gay video of interest that gets released, and very often I buy videos without knowing anything about the film. Sometimes, this makes for a pleasant surprise - Aimee & Jaguar, It's In The Water, Urbania and Normal are all examples of excellent gay titles that I stumbled upon accidentally. So when I read on the box that BEN AND ARTHUR concerned a conflict between gay lovers and the Christian Right, one of my favorite subjects, I decided to take the plunge sight unseen, despite my previously disappointing purchase of another CULTURE Q CONNECTION title, VISIONS OF SUGAR PLUMS. That film was pretty bad, but compared to BEN AND ARTHUR, it viewed like GONE WITH THE WIND. So what was so wrong with BEN AND ARTHUR? Plenty! To begin with, the "plot" such as it was, was totally ridiculous. This film almost made me sympathetic to the Christian Right we are asked to believe not only that a church would expel a member because his brother is gay, but that a priest would actually set up a mob style execution of a gay couple in order to save their souls (like this even makes sense). The writing is so poor that many scenes make no sense at all, and several plot points reflect no logic, follow-up or connection to the story. Murder and violence seem to be acceptable ends to the gay activist / right wing conflict on both sides, and the acting is so bad that it's difficult to imagine how anybody in this film got hired. The characters who are supposed to be straight are almost without exception clearly gay - and nelly stereotypes to boot; the gay characters are neither sexy nor interesting. This film is enough to put off anybody from buying gay themed videos forever, and the distributors should be ashamed of themselves. The only advantage this picture has over my other CULTURE Q Connection purchase, VISIONS OF SUGARPLAMS, is that this one has a soundtrack with clear dialogue. Hardly a distinction, since the script is so insipid that understanding the script only serves to make you more aware of how bad this film truly is. It is an embarrassment to Queer culture, and I intend to warn everyone I possibly can before they waste their money on it. At $9.95 this film would have been way overpriced; I understand that it's soon to be re-priced under $20, which is STILL highway robbery. I paid the original price of $29.95, and I never felt more cheated in my life. The only true laugh connected with this drivel is the reviews I have seen "user reviews" for this film on numerous websites, and there is always one or two that "praise" the director / writer / actor in such a way that it's obvious that the reviewer is a friend of this Ed Wood wannabe. How sad. How desperate. I just wish IMDb would allow you to assign zero stars - or even minus zero. If ever a film deserved it, this is it. Question: is it a negative review?
Example Output: yes

Example Input: Review: Jonathan Rivers (Michael Keaton) suddenly becomes a widower when his wife dies. Soon after, he's approached by a Dr. Price, an expert in Electronic Voice Phenomena (EVP), who claims he's been receiving messages from Jonathan's departed wife Anna via sundry electronic gadgets. Is Anna trying to tell Jonathan something? Is this merely a hint of something on a larger cosmic or otherworldly scale? It's good to see Keaton in a leading role, but the story he's stuck with is convoluted and absurd at points; it's as if the movie doesn't know how to answer any of the questions it brings up, so it just distracts the viewer with new, unrelated questions.Keaton himself is pretty good, convincingly cast as the bereaving widower desperately trying to communicate with his late wife. He's matured quite a bit as an actor, leaving behind the frat-friendly waacky-hijinks roles he played 15 or so years earlier. He looks a little craggy, with a perhaps few more wrinkles than one might expect, but he's lost none of the guile and panache that he's shown during his quarter century in Hollywood.So it's not that Keaton turns in a mediocre performance, it's that the script itself is subpar. Written by Niall Johnson, the plot gets more confusing as it progresses, each tortuous path ending in another tortuous path. This is all well and good if the path leads to some sort of acceptable denouement, something that ties more or less everything together and explains... something. But not White Noise; I knew less about what had happened to Jonathan than I did before I'd first seen him.Keaton's really the only reason to watch this junk, although he gets fine support from Ian McNeice (as Dr. Price) and Deborah Kara Unger as the requisite love interest.
