Example Input: Review: Having seen CUBE, I've been a fan of Vincenzo Natali's work. Natali seems to have this inept ability to take a storyline, and hardly wring it our like a wet towel for all the storyline he can muster. Instead, he lets the stories themselves unfold in natural ways, so much in fact, that you may in fact believe there is this Cube were people try to escape, or in the case of NOTHING, a large empty expanse where there is... nothing! The advert had me hooked instantly. It seemed so simple! Take two characters who no one likes, and send them to a world where there is nothing. Natali does this so simply that you forget the logic that a place where there is nothing cannot exist. In fact, the world of nothing becomes something of an irony within the film. There's nothing there, but also 'something' there.It might be a good time to point out that the trailer is highly misleading. I was fortunate enough to actually understand that the film leaned to a more comedic side than the trailer otherwise told so. Therefore upon watching the film, i laughed every now and again, whereas someone who the advert mislead may find themselves utterly confused.If i may take a minute to give the film some praise, where the film excels on is the concept. It is a genius concept to have a world of nothing, and to put two characters there, NOT two brilliant minded characters, who will philosophise and work out their surroundings, but two idiots who have absolutely no clue as to where the hell they are! Another strong point is the film's cinematography, though at first this may not seem it! Where each wall, north, earth, south, west, up and down is just a white plane, a perception of depth becomes faulty. It is hard to determine where things are placed in the Mis-En-Scene. The cinematography has many moments where this actually happens, but for the most part, the camera is placed so that two characters, or an object and a character are placed in the foreground and background, allowing a sense of depth to be realised.However, this film does lack in certain areas. The film is relatively short, but even so, after a while the novelty of this world of nothing becomes rather dull, and you wish to find some form of resolution within the plot. We can also argue that the acting is once again, questionable. These two characters are in a sense, unlikeable, therefore we feel no sympathy at any point for these characters. However, on a flip side of that, the chemistry and friendship between the two characters seems real enough, but there is something lacking.Even so, i do rank this as a thoroughly enjoyable film! Do not let the trailer fool you into thinking this is another science-fiction horror film. It is much more of a comedy than that! It is indeed worth watching though, purely for the concept itself! Question: is it a positive review?
Example Output: yes

Example Input: Review: This movie was probably the biggest waste of my life ever. The acting was pathetic. Jordan Hinson could not show any upset emotions. At the beginning of the movie, she was supposed to be discouraged. Instead, she bobbed her head with her bottom lip stuck out. She sobbed pitifully without any tears for the crying scene. I was almost angry that out of all girls who wanted to be actresses, they had to pluck out her. Everyone else was suffering from over-acting as well. It was flat out annoying. It was also an insult to figure skaters. Jordan took a month to train, and they cast her as a person who makes the Olympic team. It's practically spitting on the effort real figure skaters put into their work. A pitiful excuse for a movie, and a pitiful attempt to associate hockey and skating. Don't waste your life. It doesn't even deserve one star. Question: is it a negative review?
Example Output: yes

Example Input: Review: This is an absurdist dark comedy from Belgium. Shot perfectly in crisp black and white, Benoît Poelvoorde (Man Bites Dog) is on fine form as Roger, the angry, obsessive father of a family in a small, sullen Belgian mining town. Roger is a photographer who, along with his young daughter Luise, visits road accidents to take photos. He is also obsessed with winning a car by entering a competition where the contestant has to break a record - and he decides that his son, Michel, must attempt to break the record of perpetually walking through a door - he even hires an overweight coach to train him. Michel dresses as Elvis and has a spot on a radio show called 'Cinema Lies', where he describes mistakes in films. Luise is friendly with near neighbour Felix, a pigeon fancier. Roger is a callous figure as he pushes Michel right over the limit during the record attempt, which almost results in his death. Interspersed throughout the film are Magritte-like surreal images. It's undeniably charming and well worth your time. Question: is it a positive review?
