Example Input: Review: At first glance, it would seem natural to compare Where the Sidewalk Ends with Laura. Both have noirish qualities, both were directed by Otto Preminger, and both star Dana Andrews and Gene Tierney. But that's where most of the comparisons end. Laura dealt with posh, sophisticated people with means who just happen to find themselves mixed-up in a murder. Where the Sidewalk Ends is set in a completely different strata. These are people with barely two nickels to rub together who are more accustomed to seeing the underbelly of society than going to fancy dress parties. Where the Sidewalk ends is a gritty film filled with desperate people who solve their problems with their fists or some other weapon. Small-time hoods are a dime-a-dozen and cops routinely beat confessions out of the crooks. Getting caught-up in a murder investigation seems as natural as breathing.While I haven't seen his entire body of work, based on what I have seen, Dana Andrews gives one of his best performances as the beat-down cop, Det. Sgt. Mark Dixon. He's the kind of cop who is used to roughing up the local hoods if it gets him information or a confession. One night, he goes too far and accidentally kills a man. He does his best to cover it up. But things get complicated when he falls for the dead man's wife, Morgan Taylor (Tierney), whose father becomes suspect number one in the murder case. As Morgan's father means the world to her, Dixon's got to do what he can to clear the old man without implicating himself.Technically, Where the Sidewalk Ends is outstanding. Besides the terrific performance from Andrews, the movie features the always delightful Tierney. She has a quality that can make even the bleakest of moments seem brighter. The rest of the cast is just as solid with Tom Tully as the wrongly accused father being a real standout. Beyond the acting, the direction, sets, lighting, and cinematography are all top-notch. Overall, it's an amazingly well made film.If I have one complaint (and admittedly it's a very, very minor quibble) it's that Tierney is almost too perfect for the role and her surroundings. It's a little difficult to believe that a woman like that could find herself mixed-up with some of these unsavory characters. It's not really her fault, it's just the way Tierney comes across. She seems a little too beautiful, polished, and delicate for the part. But, her gentle, kind, trusting nature add a sense of needed realism to her portrayal. Question: is it a negative review?

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!

Example Input: Review: First of all, I have to say I have worked for blockbuster and have seen quite a few movies to the point its tough for me to find something I haven't seen. Taking this into account, I want everyone to know that this movie was by far the worst film ever made, it made me pine for Gigli, My Boss's Daughter, and any other piece of junk you've ever seen. BeLyt must be out of his mind, I've only found one person who liked it and even they couldn't tell me what the movie was about. If you are able to decipher this movie and are able to tell me what it was about you have to either be the writer or a fortune teller because there's any other way a person could figure this crap out.FOR THE LOVE OF G-D STAY AWAY!
