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: Most book adaptations are bad but this film left out key parts of the storyline and changed the description and some characters. They rewired the storyline and combined scenes and changed the order. They added ridiculous things into it that never happened in the book and would never happen.If i hadn't read the book beforehand it would have been an incredibly dull film, it didn't make you care about the characters, like them or dislike them. It turns the characters into jokes.Awful.Ridiculous.Waste of two hours of my life. Question: is it a negative review?

SOLUTION: yes

PROBLEM: Review: One would expect a movie with a famous comedian in the lead role, to be a funny movie. This is not the case here. I laughed out loud once throughout the whole movie, and that wasn't even during the final comedy-scene (which one would also expect to be the funniest). This is one you can watch when it comes to TV, don't spend any other money renting it. Question: is it a negative review?

SOLUTION:
yes
