Review: What a delightful romp  a very competently made film that has so much charm and a feelgood factor that a lot of romantic comedies lack. Einstein is brilliantly acted by Walter Matthau, while Meg Ryan's Catherine is unforgettable  better than I have seen her in those films opposite Tom Hanks  as the young mathematician struggling to be recognized.You don't need to be a young woman to understand Catherine's struggle and feel sympathetic for her immediately, and as a young man it's easy to understand what must have gone through Ed's (Tim Robbins) mind in pursuing his true love. There's universal appeal in these emotions, even if I.Q. keeps it all light, fun and tied up nicely.Sure it's not heavy, but if you look there are some subtexts. People remember Albert Einstein as a scientist yet he was a great spiritualist; his sayings such as something along the lines of, 'If it is not impossible, then why do it?' suggest he is a believer in fulfilling higher goals beyond one's immediate grasp. In this film, there are questions of what an accident really is  such as whether Albert and his whacky sidekicks' intervention in prying Catherine away from stiff-upper-lip, loveless James (Stephen Fry  who gives this otherwise cardboard character life and you cannot help but feel for his lack of feeling) counts. How much intervention happens in our lives that we do not see, and comes across as serendipitous?And of course, we'd like to think in real life, despite what we often observe of the people we know, that we Edwards get the Catherines and Jameses have to learn how to defrost the icewater in their veins. How nice to know that it might work out in I.Q.'s innocent (and disturbingly, exclusively Caucasian) Eisenhower-era land of make-believe. Question: is it a negative review?

Review: It looks to me as if the creators of "The Class Of Nuke 'Em High" wanted it to become a "cult" film, but it ends up as any old high school B-movie, only tackier. The satire feels totally overshadowed by the extremely steretyped characters. It's very un-funny, even for a turkey. Question: is it a positive review?

Ex Output:
no

Review: As with all environmentally aware films from the 1970s SOYLENT GREEN has a rather cheesy view of what ecological meltdown is . Overpopulation means there`s too many people to feed ? I was under the impression that famines were caused by either war or failed economic policies . Stalin`s policy in the Soviet Union in the 1930s left millions dead because of famine and to this day the greatest man made tragedy was Mao`s rural policy in China which led over 30 million starvation deaths in the 1950s . And let`s not forget the great famines in the horn of Africa in the 1980s and 90s which were to do with conflicts not overpopulation . You might like to also consider that two of the most heavily populated areas on Earth , Hong Kong and Macau , have never suffered a famine in modern times . Likewise the expansion of shanty towns around cities as seen here isn`t strictly down to overpopulation - it`s down to economic factors where people flock to cities to find better paid work than in the countryside ( It`s a symptom of industrial progress - not of too many births ) so the image of the streets of New York city being too congested to walk through and of having people sleep in stairwells is somewhat laughableBut don`t be fooled into thinking SOYLENT GREEN is a pile of corny tree hugging crap because I consider this to be the best ecological film of the70s . It plays on the contempary audience`s knowledge of the world where Sol and Thorn are beside themselves with joy at finding fruit , brandy and fresh meat . Thorn gasps in amazement at having ice in his whisky , puffs on a cigarette and delivers the classic line " If I could afford it I`d smoke two , maybe three of these a day " . But it`s the visage of the euthanasia chamber that`s memorable as Thorn gazes at the images of wild animals , flowers , running water and snow covered mountains , a world Thorn`s generation has never known . This is a very haunting scene which makes SOYLENT GREEN a very memorable film , combined with the fact it features the final screen appearance of Edward G Robinson as the wise old Jew Sol Roth Question: is it a positive review?
