Example Input: Review: Jochen Hick wrote and directed this little thriller of a suspense film based on the concept that the AIDS virus was a sheep virus mutated by the government to rid the world of gays and was apparently tested on convicts in the years before the outbreak of the hideous disease. Were it not for the poignancy of the concept of the film, this would fall into the category of the many films about the ruination of the world by a rampant non-prejudicial infective organism.Stefan (Tom Wlaschiha) journeys from Berlin to San Francisco to investigate his father's scientific suppositions about the induced sheep virus and its effects of the convicts in whom it was infused. He meets with some disdain and resistance to a dead theory, but also encounters some folks who know of the theory and support his investigation. Simultaneously with his visit a series of serial murders takes place, each victim killed in a similar manner and each murder apparently accompanied by strains of music from Puccini's opera 'Turandot' which just happens to be opening at the San Francisco Opera. A police investigator Louise Tolliver (Irit Levi) and her companion cop (Kalene Parker) follow the murders while Stefan makes the rounds of the sex clubs and bars in San Francisco trying to locate men who may have been guinea pigs for his father's theory. He encounters a strange lad Jeffrey (Jim Thalman) with whom he has a cat and mouse attraction and a prominent Doctor Burroughs (Richard Conti) who seems oddly involved in the cast of suspects. How this all come to an end is the play of the film, a story as much about the search for self identity between Stefan and Jeffery as it is a case for investigation of murders.While Tom Wlaschiha, Jim Thalman and Richard Conti do well with their roles (they are the only three who have any prior acting experience in the film!), the quality of the film sags considerably by the less than acceptable minimally talented Irit Levy and Kaylene Parker: when on screen the credibility of the story drops below zero. There are some small cameos by other actors that brighten the screen for the moments they inhabit, but in all the film is drowned by the incessant replay of 'Nessun dorma' as sung by Mario del Monaco from a recording o the opera - and that seems to be the reason for making the film! Good idea for a film and some good characterizations by the actors, but there is no resolution of the initial premise that started the whole thing.

Example Output: no

Example Input: Review: This movie is a prime example of squandering great resources in a film. You've got future SNL and SCTV stars in their prime, such as John Candy, Chevy Chase, Laraine Newman, Al Franken,Tom Davis and Joe Flaherty essentially making 70 minutes of coarse, uninspired fart and racist jokes. The concept of a network from the future subverting society could have really been taken to some interesting extremes, but instead right out the gate, makes a lame, juvenile proctology joke and stays in that vein of humor the whole way.Seek out the earlier and much more subversive and witty Groove Tube or the later, hilarious Kentucky Fried Movie. This movie is only for those who want to see a time capsule of bad 70's sketch comedy movies. Question: is it a negative review?
Example Output: yes

Example Input: Review: Neat premise. Very unrealistic. What I learned from this movie is that speeding crazily out of control to go to the weekend cabin may not be the best idea after all. I loved how Bill conveniently rolls out of the car and down the hill with no injury at all! Unfortunately, the same can't be said for his gal. Oh, and the police never seemed to find the car or trace the owner of the wreck.Lots of dragged out scenes including a plain stripper (still have nightmares from that scene). Poor assistant guy and his crummy useless hand. I admit I was intrigued to see what the mysterious "thing" was behind the door, but when it appeared, I just laughed. HA HA HA!! The girl really seemed sadistically angry about being revived. Personally, I really would want a new body after an excruciating experience like that! Question: is it a negative review?

yes
