[EX Q]: 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?
[EX A]: no

[EX Q]: Review: This is a great movie for all ages. Its the story about three animals how have to find their way home. There is a bit of a twist at the end and mainly throughout the whole movie. You never know what is going to happen next. This movie makes you cry and makes you laugh. You just don't know what going to happen next. The trek home is all beautiful with all the wonderful wildlife scenes. They producers also spent a lot of money for this movie and it shows too. The animals in this movie were well trained and are great actors/actress themselves. Everything about this movie is great! 10 out of 10 the whole way! Rent or buy it today I can guarantee you will love it the whole family will! Question: is it a positive review?
[EX A]: yes

[EX Q]: Review: These two men went thru hell and beyond and have produced the movie that conveys the terror that many did not survive. This is definitely a movie about survival, but not without it's touching moments.The finest piece of work I have seen documenting the 9/11/01 tragedy of New York City. Question: is it a negative review?
[EX A]:
no
