PROBLEM: Review: This is one of the most boring horror films I have ever seen, as it's absolutely god awful, John Carradine has very limited screen time. All the characters are boring, and the story is terrible, plus I could see the two twists at the end coming miles away!. The great setting and the creepy house definitely would have helped if it wasn't so damn boring, and there isn't one character to root for either, plus I hope it makes it's way to the bottom 100, because it deserves to be there in my opinion. When John Carradine finally shows up at the end, it's a pretty good scene but it's already way too late, and the only other screen time he had was in flashbacks, plus the only really gory scene in the movie is when a character gets his face messed up by Bee's, as it was rather gory. I got this in a DVD Horror set called Back From The Grave and everyone really overacts in my opinion, plus it's lucky this was included in a set I bought otherwise I would have chucked this out the window!. This is one of the most boring Horror films I have ever seen, as It's absolutely god awful, John Carradine has very limited screen time, and I say avoid it like the plague!, you don't want to go through the torture. The Direction is absolutely terrible!. Carl Monson does an absolutely terrible! job here, making every thing look cheap, wasting his potential on making creepy atmosphere and just keeping the film at an incredibly dull pace. The Acting is just as bad. John Carradine is good in his scene, but other then that he's hardly in the film other then flashback scenes. (Carradine Ruled!!). Merry Anders overacts here terribly as Laura, as she didn't convince me at all. Ivy Bethune is OK, and somewhat creepy, but also overacted, she did have a creepy smile at the end though. Rest of the cast, I didn't pay enough attention too, as I had a lot of trouble getting through it, but they were all really bad. Overall please avoid this,It's not worth the agony!.

PROBLEM: Review: I saw Brigadoon on TV last night (12 Sept 2009). I am 61 years old and have been watching films as long as I can remember. I can truthfully say that Brigadoon stands alone as by far and away the worst film I have ever seen. The accents were shameful. The local children's club would have produced better sets. The characters were so wooden that they probably contracted dry rot from the tears of the patrons who had the misfortune to watch them. It is to be hoped that the stars of this film had hides thick enough to protect them from the embarrassment which they must have suffered on seeing this film. The owners of this tripe should perform a great service to mankind and destroy all copies of this film. Question: is it a positive review?

SOLUTION: no

PROBLEM: Review: Skullduggery is a strange, strange film based on the novel "Ye Shall Know Them" by Vercors. To unleash criticism at the film feels really unkind, since it is a movie that deals with earnest themes like humanity, and pleas for upright moral standards and tolerance. But in spite of its honourable intentions and its well-meaning tone, Skullduggery simply isn't a very good film. For me, the main problem is the terribly disjointed narrative which can't make its mind up how best to convey its message. The first half of the movie is like watching a standard jungle expedition flick of the Tarzan ilk; later it teeters into sci-fi fable; by the end it slips into courtroom melodramatics. The differences in tone between each section of the movie are too great, too jarring, to overlook. They stick out like a sore thumb and remind you constantly that you're watching a muddled, disorganised movie.An archaeological expedition into the jungles of New Guinea is led by adventurer Douglas Temple (Burt Reynolds). One of the main archaeologists involved in the excursion is attractive lady scientist Dr Sybil Greame (Susan Clark). After an arduous trek they stumble upon a tribe of strange ape-like creatures. These primitive, long-lost people are covered in hair and have survived for centuries without being in any way touched or influenced by the developments of modern man. There is some evidence that they may the ancestors of early man  the "missing link" in the evolution of apes into humans. Or perhaps a race of humans who simply look and behave differently from usual? Or even a race of animals that have begun to develop human characteristics? The archaeologists call the tribe "the Tropi" and are initially thrilled by the implications of their discovery. But things take a devastating turn when nasty opportunist Vancruysen (Paul Hubschmid) declares his intention to exploit the tribe and their idyll on behalf of developers. He questions whether the Tropi are truly "human" and takes his argument to the courts, where he hopes to be granted legal backing so that his own greedy ambitions can be continued.This was a very early film in Reynolds' career, and he actually unbalances this movie by acting like he's in a comedy while the rest of the cast take it all very seriously. Not that Reynolds can be blamed  he has an impossible role, asked to play a charming adventurer who really belongs in a Tarzan flick. His character and the film are not relevant to each other. Clark fares much better as the earnest lady archaeologist, and there are nice supporting roles for British actors Edward Fox, Alexander Knox and Wilfrid Hyde-White. A major shortcoming in Skullduggery is the lame and ineffective make-up used to give the Tropi their strange hairy appearance. Rather than making the actors look like believable hominoids, the stuck-on hair merely makes them look unintentionally comical. and that's just not the right idea. We're meant to feel great sympathy for these creatures, but that's awfully hard when they look so unconvincing. Skullduggery is a failed attempt to tell a story that could have been poignant, philosophical and stimulating. The honourable intentions are there for all to see, but the end result doesn't do them justice. A worthy failure it might be but a failure nonetheless. Question: is it a negative review?
