Review: The past creeps up on a rehab-addict when he reconnects with his ill brother and a former girlfriend after what he hopes was his last stint in detox. "Life's dramas", presented here in the most simplistic way imaginable (not even the writing has any bite or wit). The cast is made up of attractive looking actors smiling glumly at one another, and the music and photography are lugubrious (a couple of the visual effects are laughable, indie-cliche touches that reek of a puny budget). Although written and directed by a man, this was produced by a woman, and I'm not sure but I think this may be a distinct reason why this picture about two men, estranged brothers growing closer, never quite gels, never feels natural or seems lived in. It's an attempt to get inside a male relationship, but the careful, sterile presentation is a cheat. No one's heart is in this, living, breathing, or bleeding this material. "The Perfect Son" is quickly diffused by too many cooks in the kitchen. Question: is it a negative review?

Ex Output:
yes

Review: This apocalyptic zombie film tries to be vicious and shocking; but FEEDING THE MASSES comes off lame as some of the stiff-legged zombies stalking the streets. In Rhode Island, a zombie epidemic known as the Lazarus Virus is being played down by the government manipulated newspapers and television stations. A couple of brave, but dumb, souls at Channel 5 TV News feels its audience is being given false hope and no idea of the real danger at hand. An eager reporter(Racheal Morris)and her cameraman(William Garberina), with the aid of a military escort(Patrick Cohen), risk life and limb to present a 'live' broadcast to show the doom at hand. Do yourself a favor and don't watch. This thing is obviously very low budget and comes across with the feel of a high school play gone bad. Acting is atrocious and the flesh-hungry zombies are almost comical. Also appearing are: Michael Propster, William DeCoff and Brenda Hogan. FEEDING THE MASSES should be left to starve. Question: is it a negative review?

Ex Output:
yes

Review: When I saw this "documentary", I was disappointed to see Serbian Propaganda in action once again. Even though Serbia and its nationalist politics is main reason of Yugoslavian breakup, it is not mentioned in this "documentary", which is made by Bogdanovich whose name tells us that he is Serbian and his movie that he is far from being objective. It is one in the set of lies pushed by Milosevic regime. Everyone else is guilty only Serbians were right and victims, even though most of the War Criminals tried in Hague are Serbs, even though Serbs are one who have committed genocide against Bosnians , and attacked Slovenia, Croatia,and Bosnia all independent nations recognized by the UN.Breakup of Yugoslavia was not avoidable because Serbians did not want to release the grip their nationalism has put on Federal Yugoslav government, so SLovenia, Croatia, Macedonia, and Bosnia were forced to become independent nations in order to protect their interests.If you are interested in an objective documentary about breakup of Yugoslavia, and fact led documentary this is not it . You should watch "Yugoslavia:Death of a Nation", Made by Discovery channel and BBC. Question: is it a positive review?

Ex Output:
no
