[EX Q]: 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?
[EX A]: yes

[EX Q]: Review: The producers of this film offer to pay funeral expenses for anyone who dies of fright while watching this movie. They should have offered intensive psychotherapy for anyone who really enjoyed this stinker. A young couple moves into a house, where a woman who looks like the woman from the couple lived. Extremely boring, and very predictable. In the end I ended up not caring about anyone in this movie.Avoid this one at all costs. Question: is it a positive review?
[EX A]: no

[EX Q]: Review: I was really stunned how much a film, that's over 60 years old could impress me. It is nearly two hours long, there are absolutely no stars in it, there are subtitles but nevertheless it is interesting and exciting to watch. What impressed me mostly was the realism of the film. You could nearly feel the coldness of the ice, because you could see that the storms are real. This is a relief in a CGI-world like ourdays. I wondered how much work this must have been for van Dyke. I read somewhere that it took 17 months to film it. Now who wants to talk about 'Titanic' anymore? It's a great film with a great message and I would recommend it to future directors to see how great and realistic movies can be if they are only directed with realism instead of visual effects. Question: is it a negative review?
[EX A]:
no
