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 Output:
no

Review: I would almost give it 10 out of 10. However, there are some confusing parts as well as sections that are miss-leading which hurt the flow/continuity of the film. The story line is great and well composed; you will definitely want to watch this quietly to fully understand it. The characters are complicated and so is the story line, expect to be given only enough information to stop scratching your head, it's a film where all is explained in the end. The animation is great and the combination of femme fatal and film noir result in a great film that is unlike anything else I've seen in animation. It is a black and white film and its quiet dark in a few scenes so it's worth watching it on a good T.V, or plasma. The character voices do save this film in its English version, but it would have been more convincing if there were some French accents to emphasize that its happening Paris, I enjoyed it more in French with English subtitles. One the whole its well worth buying on DVD or BlueRay if they have it! And personally if you enjoyed this film you might also like; Waking Life & Ghost in a Shell 2 Innocence, this is just a personal suggestion. Question: is it a negative review?

Review: This is a film that was very well done. I had heard mixed reviews while it was in production and have been waiting for its release! Cheers to the director and all the actors. The supporting cast gave Eva Mendez what she needed to take this to the top. As everyone else here states, the latter portion of the film is riveting. Katie Cassidy did an amazing job with her character, being she had not done a lot of work when this film was made. She has quite the career ahead of her. I was amazed at her performance. I completely enjoyed the film, questioned my values in life and priorities, and am a better person for it! A great message lies within the film. Release it so all can enjoy!
