Example Input: 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?

Example Input: Review: I really enjoyed this film because I have a tremendous interest in American History... the Antebellum years and the Civil War in particular. I purchased it recently from a rack of previously-viewed videos on sale at the supermarket and I was very glad to add this one to my history video collection. Though not of the caliber of Civil War films such as "Glory" or "Gettysburg," provides a lot of history on the pre-Civil War brotherhood among cadets at West Point.Maybe it's the gray uniforms, the youth, or the military discipline, but I am fascinated by the story of the Corps of Cadets from around 1830 to the brink of the War. I imagine what it must have been like to sit in a classroom with other young men, learning how to make war, then later putting the lessons to use against your own classmates!Actually, there were two classes graduated in 1861: one class in May, the other in June. the movie makes no real mention of this, except to mention Henry A. DuPont, first graduate of the May Class; and George Custer, last grad of the June Class. the reason for the two classes was not so much about the war, but it was the result of switching back to a four-year course of study, after a few years of experimenting with a five-year course (I think the first class had attended five years, the other for four). As the movie portrays, cadets were like brothers and often had nicknames for each other... George "Fanny" or "Autie" Custer; Alonzo "Lon" Cushing; James "Beauty" Stuart (for J.E.B. Stuart, class of 1854), etc.I say this film is "Santa Fe Trail" as it should have been because that 1940 film, while enjoyable, really fudges history. Cadets from several different classes are all graduating together. JEB Stuart and George Custer are portrayed as the best of friends and are side-by-side in stopping John Brown's 1859 insurrection at Harper's Ferry. In fact, Stuart and Custer were never friends, but enemies during the War. They faced each other (for the first time, I think) at Gettysburg in 1863 (Stuart was at the Harper's ferry Raid, but Custer was still a cadet at the Point when it took place)."Fanny" Custer plays a role in "Class of '61," though his classmate chums, Dev O'Neill and Shelby Peyton are fictional. I believe they are respectively based on Partick Henry O'Rorke and John Pelham, two people you can look up.Anyway, I truly enjoy this film or any film which provides a window into mid-19th Century America.

Example Input: Review: Midnight Cowboy made a big fuss when it was released in 1969, drawing an X rating. By today's standards, it would be hard pressed to pull an R rating. Jon Voight, who has been better, is competent in his role as Joe Buck, an out of town hick wanting to make it big with the ladies in New York City. He meets a seedy street hustler named Ratso Rizzo, who tries to befriend Buck for his own purposes. The two eventually forge a bond that is both touching and pathetic. As Ratso, Dustin Hoffman simply shines. Hoffman has often been brilliant, but never more so than in this portrayal. He is so into character that all else around him pales in comparison. Losing the Academy Award to John Wayne is one of the most ridiculous decisions ever made by the Academy of Motion Picture Arts and Sciences. Director Schlessinger has a deft hand with his production, but this film has a grungy underbelly that leaves a bad taste in the mouth of the viewer. Worth seeing for Hoffman's performance alone.
