[EX Q]: Review: So, not being a poet myself, I have no real way to convey the beauty and simplicity of this documentary. The effortless motion of Goldsworthy, as he molds natures beauty into his own work is captivating. Watch him stick reeds together in a web hanging from a tree in a close up for a few minutes while he speaks of his work, and then receive the payoff when the camera cuts to the wide shot. Be amazed by the ease with which he operates and then realize the futility when a slight breeze knocks down the entire web.The genius of Goldsworthy seemingly knows no bounds as his inspiration is nature itself. It is in the essential change of nature where his work, though complete in its own sphere, is made whole. Question: is it a positive review?
[EX A]: yes

[EX Q]: Review: While originally reluctant to jump on the bandwagon of watching "Lost", I accidentally caught one episode at the beginning of season 1the one with the polar-bearand it has had my undivided attention ever since. The show, that is. Not the polar bear. So bear (heh) with me while I throw out as much rambling, semi-coherent praise as I can muster."Lost" takes a simple idea of a passenger flight full of people crashing onto a desert island, and gradually adds extraordinary depth to its premise by exploring each character deeply and unflinchinglywhat drives them, who are they? Where did they come from? It soon becomes clear that the island upon which they are stranded acts as a common denominator for many things in their lives, whether they're running away from something (Sawyer and Kate among others) or getting in touch with spirituality (Locke, Claire). But "Lost" also zooms in on the island itself and the mysterious horrors that it houses... and they all seem to be strangely connected.While television actors are not exactly known for their subtlety or dazzling acting abilities, most of the cast of "Lost" are, in truth, spectacular actors for their respective parts, projecting heart and humour in their performances. There's also a multitude of eyecandy, but not generally of the plastic Hollywood kind as most TV shows. The characters all feel very real and they are extremely compelling to watch. Their interactions rarely fall prey to predictable sappiness, petty arguments or cheesy melodrama (although they are annoyingly secretive)  these people are first and foremost trying to survive and whatever relationship appears is treated secondary to action. The realism of these characters facilitate an already well-sculptured plot. About this plot... Imagine a tree as the template plot, then the branches as subplots (in this case, one branch for every character)  well, Lost adds twigs to each branch and then tiny twigs to those twigs as other story lines. If you're a brother/sister to one of the main characters in the flashbacks, you will get your own storyline. If you're a DOG you will have your own storyline. Unless the writers manage to weave them all together into some glorious culmination in the end, they are setting themselves up. I am more than a little worried there will be some disappointing cop-out to this show, as I'm sure most people are.But assuming the writers do pull this off, "Lost" is possibly the best show ever to hit television.9/10 Question: is it a positive review?

[EX Q]: Review: If one sits down to watch Unhinged, it is probably because its advertisements, video boxes, whatever, scream that it was banned in the UK for over 20 years (as virtually every video nasty does). It's true; exploitation and taboo excites people and draws them in with their promise of controversy. Being an exploitation fan, however, none of this was new to me. The advertisements that scream that the film was banned in the UK don't necessarily make me want to watch it; in fact, the first thing that usually pops into my head is how disgustingly paranoid British censors are. How I came to viewing this then is simple: it promised gore and it was only $6.99. The price alone alerted me not to have any hopes of this being the next Halloween, but a cheap padding of your DVD collection never hurts. I did force myself, however, to watch it all in one sitting, because I find that deciding to save the rest for another day makes you even less inspired to finish it. So anyway, after 90 minutes of Unhinged, I found that I had come across the cheapest sleeping aid in existence. I think the distributors could make a fortune if they simply changed their marketing technique.The layout of Unhinged is of any common slasher from the 80s. There's unnecessary shower scenes and exploitative gore. That's about it. Anyway, it starts with a group of three attractive co-eds crashing their car on the way to a concert. Though two of them (Terry and Nancy) are okay, one (Gloria) is severely injured and is out of commission for the rest of the movie. They are rescued and receive shelter at a mansion (that happens to have no phone, of course) with rather strange occupants: Marion is a middle-aged woman with a man-hating mother who constantly accuses Marion of sneaking men into the house in order to sleep with them (echoes of Psycho?). She also happens to have a crazy brother Carl who lives in the woods, because her mother's hatred for men is so intense that she refuses to let him stay in the house. After hanging with Marion for awhile, Terry (our "hero") and Nancy decide they must contact their parents. Despite everyone's warnings, Nancy braves the dangerous woods to make it to a phone (her fate is not hard to predict). After that, we see Gloria again, who is then promptly butchered with an ax. When Terry discovers that Gloria has disappeared from her room, she decides something isn't right with this picture and sets out to find her missing friends. That may be easier said than done, however, with crazy Carl lurking around After viewing Unhinged, I read an overwhelming number of reviews declaring that Unhinged worked perfectly because it took its time to build its subject matter that created real tension by the time the moment of truth comes at the end. Normally, I do not drag other people's opinions into my reviews (especially when they contradict my views), but in this case, I was so puzzled by their reactions that I thought it would be relevant to mention. This is because in actuality, the film crawls. Normally for the slow-building tactic to work, the audience must have a strong sense that the characters are in danger. Oh sure, we see two of them get murdered, but between that are endless scenes of conversation and boredom. We are aware that there's a killer on the loose, but this is only focused on three times in the film; that means there's no reason to fear for the victims. Instead, the film's events are explained not by the actions of the characters, but are drawn out for us by perpetual talking. If there's one thing I can assure you from watching this, it's that scenes of characters merely conversing with each other for 75 minutes are very tedious. None of this is helped by the atrocious acting. It seems that this was another case of the director needing actors and decided to gather his friends around instead of finding anyone with experience.Of course, I'd be a liar if I said there wasn't one part of the movie that I enjoyed. Specifically, the ending was one of the best I've ever seen in a slasher film; you just do not expect that to happen. Just knowing that the director had the balls to do something like that is spectacular. Ah, I won't spoil it for you, nor will I say that the ending completely makes up for the rest of the slow-moving film, but it definitely will get your attention. Other than that, the other two murder scenes bring at least some faster paced material, but it's not like you couldn't tell exactly who was going to die fifteen minutes into the film. Anyone looking for a bloodbath will be disappointed, however; those are the only scenes of gore present. That and, of course, no one scene can save an entire movie. I normally preach the doctrine that as long as there's action, the worse a movie is, the better it gets. Unhinged only grasps one part of this concept. The whole film just feels Luke-warm; there's potential alright, but the director either wasn't experienced enough to make it work or just didn't know what the hell he was doing.
