Review: So one person says, "This movie is a beautiful, delicate exploration of West German life after World War II."

Just see it." Question: is it a negative review?

Review: This is such a fantastic movie, a Western about a self-concerned man (Jimmy Stewart) going up to the Klondike for gold. On the way, he gets hassled by a local sheriff in Alaska (John McIntire, giving a wonderfully evil performance), whom he hassles back. McIntire threatens that he'll be a dead man if he ever comes back through his town, which is, unfortunately, the only way back to the States. The main chunk of the story is about the peaceful Klondike town of Dawson being turned upside down by new residents from McIntire's town. Ruth Roman, for instance, who has come with Stewart and his two companions (Jay C. Flippen and Walter Brennen, who plays Stewart's best friend), builds a saloon (a Hollywood front for a whorehouse) and tries to run the town's restaurant and hang-out place out of business. She paves the way for McIntire and his goons to come up, too. In 1953, Jimmy Stewart and director Anthony Mann made one of the peaks of the Western genre, The Naked Spur. The Far Country is just the tiniest bit less, and it contains 99.9% of what made that film so special without, of course, feeling like a cheap copy. Like The Naked Spur, The Far Country boasts beautiful, on-location cinematography. The landscape is gorgeous. Stewart gives one of his best performances (nearly equal to his biggest success of 1954, Rear Window). I suppose it could be considered cliche, as he starts out a selfish loner and learns how that kind of existence plays out in the end. Still, Stewart plays it so damn well, he makes this character very human. And the supporting performances are universally fantastic. In addition to those I've mentioned, the adorable French actress Corinne Calvet is very good. And I ought to single out Walter Brennen, as well. He seems to have specialized in playing best friends. His relationship with Stewart is very touching, since he is, at first, the only character who is able to bring out any humanity in the cynical man. The screenplay is very well written, and Mann's direction is impeccable. A masterpiece. 10/10. Question: is it a positive review?

Review: Nightmare Weekend is proof positive that some people are so desperate to be 'in the movies' they are prepared to do almost anything.I'm not referring to the countless women who seem quite happy to appear completely starkers in this dreadful piece of trash (after all, the naked female form is a beautiful thing and nothing to be ashamed of). No...I'm talking about those who are more than willing to co-star with a badly made hand-puppet called George. Now that is embarrassing!!!A bio-electronic being created by brilliant scientist Edward Brake (Wellington Meffert), George (who looks like a demented felt clown with green wool for hair) is the artificially intelligent interface for an advanced computer system that operates a revolutionary device (a silver sphere about the size of a golf ball) that, when ingested, can reverse character disorders.Edward's personality altering experiments have been successful on lab animals, but the cautious scientist is reluctant to carry out tests on human subjects, fearing that there may still be side effects. His evil assistant Julie (Debbie Laster), however, has no such qualms, and proceeds to use three beautiful young women as guinea pigs. Inevitably, they all turn into hideous killer mutants.With bargain basement special effects, a cast totally devoid of talent, and a plot that is almost impossible to follow (I took notes as I watched the film, and even then I am not entirely convinced that my synopsis is accurate), Nightmare Weekend is a complete and utter disaster that not even several soft-core sex scenes and a touch of gore can rescue.This film also features one of the most irritating characters I have ever seen in a horror movie: Tony (Bruce Morton), a Walkman wearing idiot who bops away to crap 80s music in a manner that makes me look like Justin Timberlake in comparison.
