Input: Consider 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!

Input: Consider Input: Review: not your typical vamp story, not bram stoker or anne rice here. a truly original vampyre story. these vampyres are genetic mutants who the sunlight don't bother. they are pure evil to. the film is not perfect. many of the actors are clearly amateurs. the two leads who play van helsing and rally the vampyre chick are pretty good though. the film is intensely violent which may disturb some people. also it is loaded with scientific detail that many will find hard to understand and may get bored with. i was sold on the clever storyline and the couple good performances. no telling how successful this film could be if they had a bigger budget and it got mass distribution Question: is it a negative review?

Output: yes


Input: Consider Input: Review: This might be the poorest example of amateur propaganda ever made. The writers and producers should study the German films of the thirties and forties. They knew how to sell. Even soviet-style clunky leader as god-like father-figure were better done. Disappointing. The loss of faith, regained in church at last second just in time for daddy to be "saved" by the Hoover/God was not too bad. Unfortunately, it seemed rushed and not nearly melodramatic enough. A few misty heavenlier shots of the angelical Hoover up in the corner of the screen-beaming and nodding- would have added a lot. The best aspect is Hoover only saving the deserving family and children WHO had "proven" their worth. Unfortunately, other poor homeless were portrayed as likable and even good- yet the Hoover-God doesn't help them. A better approach would have been shots of them drinking spirits to show the justice of their condition. Finally, bright and cheerful scenes of recovery (after Hoover saved the country from the depression) should have rolled at the end. We could see then how Hoover-God had saved not just THIS deserving family, but all the truly deserving. Amateurist at best. Question: is it a positive review?
