Review: not your typical vamp story, not bram stoker or anne rice here. a truly original vampyre story. these vampyres are genetic mutants who the sunlight don't bother. they are pure evil to. the film is not perfect. many of the actors are clearly amateurs. the two leads who play van helsing and rally the vampyre chick are pretty good though. the film is intensely violent which may disturb some people. also it is loaded with scientific detail that many will find hard to understand and may get bored with. i was sold on the clever storyline and the couple good performances. no telling how successful this film could be if they had a bigger budget and it got mass distribution Question: is it a negative review?

Ex Output:
yes

Review: When it comes to Paul Verhoeven and erotic thrillers, most people think of "Basic Instinct" and some maybe of "Showgirls". But Verhoeven has made his best erotic thriller years before these two movies: "De Vierde Man". This film is mesmerizing and mindblowing - and above all the story is absolutely plausible, which makes the whole experience even more intense. The performances by Jeroen Krabbe, Renee Soutendijk and Thom Hoffman are exceptional, and Verhoeven's direction does the rest. "De Vierde Man" makes even "Basic Instinct" look quite tame... It can't get much better than this, a true classic of erotic nightmare cinema. 10 out of 10, at least... Question: is it a positive review?

Ex Output:
yes

Review: Special effects? Good.Script? Terrible. No plot. No depth. No meaning. This film rendered Superman as a meaningless hero, a hero with no archetype. In the original film, he represented America in the Cold War. Here, he represented nothing but a Hulk.Sure, the actors were fine. Kevin Spacey was a fine choice, among others.This still does not resolve the problem that this film had no depth whatsoever. I cannot see how anyone can come away with anything meaningful from this film, when Superman was, and is, daily created to be a meaningful hero in not only comics but also in people's minds. This was a real waste of money considering how many directions this film could have taken.Just a few instances: Lex Luthor could have been a villain of global corporatism, political domination, totalitarianism, and on and on and on. He was just another goofball Hackman incarnation.And Superman? For what did he stand in this film? Nothing but another hack "savior" figure.Wait until it comes to the dollar theater if you see it at all. Question: is it a negative review?

Ex Output:

yes
