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: A great idea: 11 stories about 11 September. 11 directors from different countries with different results. Ken Loach talking about an immigrant (as usual) is just brilliant (as usual). The Frenchman does a very good job also, while the Burkina Faso film was a nice surprise. However, the Israel film was a bit boring, and the Mexican guy, well, he should quit directing and work in a Mexican restaurant. 8/10 Question: is it a positive review?
Example Output: yes

Example Input: Review: Firstly, this is a very dated film, non-focused in its exposition of the left wing political revolution. Honestly, when someone says that the only way to be truly revolutionary is to cease to be intellectual ( which in itself is quite nonsensical, since the answer was arrived at by precisely being intellectual) it reduces me to despair; as if we all should return to being apes in the name of equality - it is simply ridiculous. Our intellectuality is only one of many human qualities, but this does not mean we should not educate ourselves to the highest possible degree. But no doubt this non-educational message ties in with Godard's use of rock music; hence The Rolling Stones.The song 'Sympathy for the Devil', whose creation we witness, and from which the film takes its name, is in fact nothing special. The chord sequence, which is not especially original, was used to much better effect in Led Zeppelin's 'Thankyou'(Led Zeppelin II). Apart form that, 'Sir' Mick Jagger declaims in his usually nebulous manner (rather like Bob Dylan)- notice how the first melodic phrase is unimaginatively repeated over again to form the verse.Besides the fact that the Black Panthers depicted in this film, don't seem to know what they are fighting for, the most interesting scenes involve the equation of fascism with pornography; a message that in fact undermines the sexual 'liberation' of the 1960s and today ( indeed, a message that would belie the behaviour of The Rolling Stones around the time the film was made).No wonder, the DVD came free with The Sunday Times! For a truly profound historical exposition of left-wing sympathy, listen to Luigi Nono's masterpiece, 'Al Gran Sole carico'd'amore'. Question: is it a positive review?

no
