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: One of the five worst movies I have ever watched. And I'm not exaggerating. In fact, I recommend watching it so you can get the same feeling of incredulity as you might by watching Showgirls.Out of 400 votes, the movie gets a user rating of 5.3/10. But there is a disproportionate number of voters who gave it a 10/10, probably due to the message of the movie - nuclear weapons are the bane of mankind. Chuck Murdock is an all-star little league pitcher who gives up baseball because there are nuclear weapons. Soon "Amazing Grace" Smith is an all-star Boston Celtic who is inspired by Chuck's story and gives up basketball. Soon all sports leagues from the professional level to college to high school to little league dismantle in a world-wide protest. Later all the children of the world go on a silence strike. This inspires the President of the United States to meet with the Soviet Premier, who in time agree to eliminate all nuclear weapons in time for the start of the next Little League season. The movie ends with Chuck about to throw out the first pitch, with the President telling his new best friend Chuck not to worry about striking out every batter, as he hasn't thrown a baseball in a year.Somewhere along the line a nefarious underworld boss kills Amazing Grace. When the President finds out he is told that the FBI can verify the killer but will never be able to prove it. So the President calls the underworld boss ("But it's one a.m." "I don't care, get him on the line") and tell him that he is to resign from all company boards that he sits on and sell all stocks that he has. And to not get out of line again.Honestly, this movie was so crappy that I couldn't turn it off. It was on television from 2:30 am to 4:00 am, and I watched it all. I wasn't turned off by the anti-nuclear weapons propaganda. I was turned off by the implausible break down of all organized sports. I don't even understand why "Amazing Grace" Smith was killed. And with all these famous athletes becoming Chuck's friends, why the father was constantly upset with his son taking a principled stand. And there was the cliche moment near the end when dad tells Chuck, "I never told you this, but I'm proud of you." Cue hug. Question: is it a positive review?

Review: One of the worst movies I ever saw. My only thought was: "how can I get my money back from Hollywood Video". This is no way worth four dollars, or any dollars. I think it was an attempt to rip off The Mexican, or Vin Diesel's movies, but it failed miserably to do this.The acting was terrible, I felt sorry for the actors that they couldn't find something better to do with their time. The story was ridiculous. We were calling out the lines ahead of the actors, it was so predictable. The Mexican accent of the leading lady was insultingly exaggerated, worse than a cartoon. Skip it.
