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: I had to register for IMDb just to post a comment on just how awful this movie is...my cats and a ball of string have a better storyline than this. Not the worst acting I've ever seen, but when you wipe out almost the entire cast of the movie within 5 minutes, it leaves a bit to be desired. There wasn't a single 'scare' moment in the movie, with the exception of when they were watching the movie 'Halloween' on the TV. All around, it seems like it could've been a good story, rolling the credits and saying that Chasey Lain was in it was a bit of a loss as I didn't recognize her right away and her scene was already over before I could've said 'oh yeah, there she is'. I'm so glad I saw this in a hotel and didn't pay for it as I'd be real ticked if I had payed a cent to see this. I normally like or can at least find a redeeming factor in a movie, but this one is an exception. It's so bad that it's not even that amusing so-good-it's-bad....it's just plain bad. Question: is it a negative review?

SOLUTION: yes

PROBLEM: Review: Remembering the dirty particulars of this insidiously vapid "movie" is akin to digging into your chest cavity with a rusty, salted spoon. Perhaps "Home Alone 2: Lost in New York" (1992) was a bit on the predictable side, but this pathetic excuse for a film is just one of the most shameless bids at commercialization I have ever heard of. A boy fighting off spies/terrorists when he's home alone in a Chicago suburb with the chickenpox? Ridiculous! Why did this film have to be made? I am the kind of person who believes even terrible movies are not wastes of time, but rather learning experiences. However, this is actually a waste of time. It should be avoided at all costs. Question: is it a negative review?

SOLUTION:
yes
