Review: John Rivers' life as an architect and family man has taken a turn for the worst when his wife has disappeared and has been concluded dead after a freakish accident that involved changing a tyre on her car. During the days she has been missing, he confronts a man that's been following and he tells him that his been in contact with his dead wife from the other-side through E.V.P - Electronic Voice Phenomenon. Naturally he doesn't believe it but then hear gets weird phone calls from her phone and so he contacts the man to find out more about E.V.P. Soon enough John is hooked onto it, but something supernatural doesn't like him interfering with the dead, as now other then contacting his wife, the white noise is foretelling events before they happen.Since this DVD has been sitting on my shelf for a while now, I thought I better get around to watching it since it wasn't my copy. But then again I don't think the owners were in a hurry to get it back, as they haven't question me about it. Oh well. So I decided to give it a play, as I was in an undemanding mood. After hearing and reading all the bad press on it, I wasn't expecting anything remotely good, but I was kept entertained for 90 minutes. Well, more so the 60 minutes, as the last half-an-hour was pretty much a blur of confusion. The film is nowhere as good as it could have been, but the time breezed by quick enough even though it's a rather tepid supernatural thriller. I thought it wasn't all a waste. The first hour I found some effective sequences rather interesting and there's a spooky awe generated with a slow progression of subtle stillness and tragedy that haunts you, but sadly that comes to a crashing halt later on in the film. That's when the predictably forced jump scares come into their own and somehow it just doesn't fit in with the context. It becomes rather hectic, loud and very muddled with its MTV style editing and kinetic camera-work that gets to close into the action. I couldn't understand what was going on within choppy and abrupt climax. The whole explanation how everything fits into the bigger picture is pure hokey. It's a very unsatisfying conclusion because it goes for something big, but hits rock bottom. I thought they did fine job up until that point with the lighting and showy camera-work. Other then the distinctively stark lighting, the score kept this flick atmospherically gloomy. All of it is very slickly done with its glossed up and fancy hardware, which makes it come across as very sterile and empty.You can easily see that the film's heart is in the technical components and not in expanding the characters and story. There's just no connection and lasting sentiment within this flimsy material. After a while, it just tries too hard to convince you that it falls into manipulative thrills and popping in many blood-curdling stuff from beyond the grave. It just got rather repetitious watching someone watch a fuzzy TV screen after while. The E.V.P machine was the star on the show. Well, it did have more impact than the limp performances. Michael Keaton is more than capable actor, but lately his disappeared off the map and here he provides a modest performance as the dangerously obsessed John Rivers. He really deserves much better, though. Everyone else is pretty brittle and forgettable. Not because of the performances, but of the lack of depth in their characters. This clunker wasn't bad to begin with, but it does go pear shape by falling away drastically.I wouldn't care to see it again and I wouldn't recommend to anyone, unless you got a interest for the subject matter and enjoy the recent crop of Hollywood produced horror/thrillers. It's just a damn shame that this over-produced flick couldn't put it together successfully, as it had promise in its idea and a more than decent cast on hand. I didn't hate it, but what a disappointment. Question: is it a positive review?

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!

Review: "Pandora's Clock" is a gripping suspense/thriller that's a cross between a virus movie and a disaster film. This movie, which aired in two parts on NBC in its debut showing in 1996, is about an airplane flight that becomes infected with a virus when one of the passengers just happens to be carrying this disease. The U.S. Government debates on whether the plane should be destroyed or not, while the pilot (Richard Dean Anderson) and a virus expert (Daphne Zuniga) try to figure something out to avoid disaster. I'm not really a big fan of TV movies and miniseries, but I liked "Pandora's Clock". It's one heck of a thrill ride. Jane Leeves (TV's "Frasier"), Robert Loggia, and Edward Herrmann (as the President) also star.*** (out of four) Question: is it a positive review?
