Question: Review: i should qualify that title, now that i think about it. Checkout is not entirely worthless. i've had the opportunity to see it twice, and on the second time i did get a great laugh at the movie's expense. so i guess it's worth something for that. and also it's worthwhile for the excruciating pain it caused me on my first viewing. as another reviewer pointed out, this film is hackneyed in every sense of the word. not a single original thought went into this movie (which makes the comment below about the originality of the premise entirely baffling to me). the film is nothing but a long line of cliches which are strung together and paraded around as a movie. it is definitely not the next Clerks, it is definitely not original, and it is absolutely not "good, clean fun." the film is absolute agony to the uninitiated (after seeing it a first time, the second time can be quite funny, in an insulting sort of way). as i looked around the theater, it was obvious that nearly everyone, barring perhaps the elderly, were completely bored or pained by this movie. during some of the particularly emotional scenes, like where Nick chews out his mother, the audience was actually cringing because it was so poorly done. i even heard someone *groan* in the theater, something i had heretofore never witnessed. i don't care where you have the chance to see this movie, be it at a film festival, or in a indie theater, or wherever. do yourself a favor, skip this movie with a vengeance. unless you're like me and just can't resist the opportunity to see what may truly be the worst movie ever made. Question: is it a positive review?

Answer: no

Question: Review: I saw "The Grudge" yesterday, and wow... I was really scared, a good thing. I love horror-movies, and I really liked this one. There were so many 'surprise'-scenes (what's the English word?) that made you jump in your seat. Though, too much screaming from the audience made it difficult not to laugh. I think the most scary scene was... on the bus, when the face flashes by on the window, or when Yoko's walking without her chin. The make-up is also VERY good. Sometimes you could really see it was there, but it was still adding a freaky look to the scene. The boy was very good indeed, so cute without make-up and so terribly scary with it on. The next time I hear a cracking noise I will probably feel pretty scared... Question: is it a positive review?

Answer: yes

Question: Review: EPSILON, a.k.a. ALIEN VISITOR, is not what I expected. This is a no-budget Australian film with no special effects other than speeded-up film and quick scene cuts. The female alien (who comes over immediately able to speak perfectly accented Australian) can "blip" from place to place or time to time and alter her perception of the flow of time to match the "faster" humans.An elderly grandmother tells her two granddaughters about a story a wandering man told her 40 years before, when an unnamed "She" came to the planet naked and completely disoriented, unable to recognize which star in the sky she came from...She meets a man alone camping in the Australian Outback, apparently bewildering him. She is here by "mistake", and gets angry when she is told she is on Earth. The Earthlings are known as consummate despoilers of the environment and a metaphor for the most insulting thing imaginable to the rest of the universe: those who "breathe the foul air" but do nothing about it, sticking their heads under the sand like an ostrich. In another amusing metaphor, Earthlings are "frogs".From there, it is entirely a film about dialogue, as the perplexed man tries to understand She's peculiar psychology and viewpoints, even as She calls him unintelligent and "quaint". The man begins to realize maybe it's humans who are irrational and not thinking straight. Yet, while waiting to be "beamed up" back home, She sees that this human is not entirely faulty in his thinking and even falls in love with him.The dialogue about perspectives is in spots interesting, but it is all layered with a heavy-handed environmental message and a low-budget feel (there are only two main actors, who blip around various deserted scenes, and the evil despoiling humans on the planet are never seen at all). The environmental message offers no solutions, but paints one or two dire metaphors about what will happen to nature and man if something isn't done. The logic also doesn't hang together: the rest of the universe has "given up" on Earth, yet one space woman caught on Earth by mistake manages to effect some positive change by the conclusion of the movie. What would a battalion of aliens deliberately sent here manage to achieve against pollution and waste? Question: is it a positive review?

Answer:
no
