question:
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?
answer:
yes


question:
Review: In the autobiographical coming-of-age tale "Romulus, My Father," Eric Bana, of "Munich" fame, plays an impoverished German émigré struggling to raise his son, Raymond (Kodi Smit-McPhee), in rural 1960's Australia. The major obstacle to the family's stability and happiness is his wife, Christina (Franka Potente), who flagrantly violates her wedding vows by shamelessly shacking up with other men. Despite her highly unconventional behavior, Romulus refuses to grant her a divorce, masochistically torturing himself in the vain hope that she will one day return to him. It is, unfortunately, the good-hearted and good-natured Raimond who must bear witness to all this marital turmoil - and it is his memoir that serves as the basis for the movie (Raimond Gaita would later grow up to be an author).Even though I admire "Romulus, My Father" for what it is trying to do, I can't honestly say I enjoyed it, for while the film has some fine performances and serious intentions going for it, these simply aren't enough to counteract the dour storyline and funereal pacing, which leave the audience as despairing and depressed as the people on screen. A serious slice-of-life drama is one thing, but this unremittingly downbeat wallow in adultery, insanity and multiple suicides (let alone attempted suicides) is something else again. Question: is it a positive review?
answer:
no


question:
Review: A wonderfully quirky film with enough twists for a sack of pretzels. Parker Posey plays Fay Grim as a sexy, vulnerable, loving mother who may or may not be what she seems. The story is very tongue in cheek, and the dialog skillfully understated. Hints of humor and intrigue, neither of which overpower the characterization Posey pulls off so well. The supporting cast is stellar. The downside? This film needs your full attention, almost to the point of stopping the film and taking notes. Posey has more sex appeal in her lifting of an eyebrow than most actresses have in their entire body. She's worth your time, even if you don't understand the denouement. Question: is it a negative review?
answer:

no
