Review: The first 45 minutes of Dragon Fighter are entirely acceptable and surprisingly watchable. The characters are believable and interesting. The cloning lab looks really high-tech. After that, it all collapses. The characters start behaving idiotically, and a new subplot is introduced from nowhere about a fusion reactor (and this is supposedly "present day") going critical, the only plot justification of which is that it is required to kill the dragon - only it doesn't. The finish is incredibly weak. One wonders what made a movie that started out so well turn so wrong.All the characters except Dean Cain are played by Russians. This results in some weird situations and details, like the character being played by Vessela Dimitrova being called "Bailey Kent" despite her heavy accent (and despite her, on one occasion, inexplicably switching to *Spanish*!).Because of the decent start, I considered rating this movie a 5, but it really was more disappointing than that, so I only give it 4. Question: is it a positive review?
no

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?
no

Review: EUROPA (ZENTROPA) is a masterpiece that gives the viewer the excitement that must have come with the birth of the narrative film nearly a century ago. This film is truly unique, and a work of genius. The camerawork and the editing are brilliant, and combined with the narrative tropes of alienation used in the film, creates an eerie and unforgettable cinematic experience.The participation of Barbara Suwkowa and Eddie Constantine in the cast are two guilty pleasures that should be seen and enjoyed. Max Von Sydow provides his great voice as the narrator.A one of a kind movie! Four stars (highest rating). Question: is it a negative review?

no
