Input: Consider Input: Review: For a first film in a proposed series it achieves the right balance. It is done with style and class showing Modesty's early days as a refugee and the start of her rise to power in the criminal world. I think it is a very honest/true portrayal of her character exactly as the writer Peter O'Donnell intended. Alexandra Staden as Modesty is stunningly beautiful and an excellent choice. She acts very convincingly as the tough survivor with an exterior of cool/intelligent/innocence. And full marks to Tarantino for choosing an unknown actress for the role - much more believeable to have a new face creating the part. I'm looking forward to the next film. Question: is it a negative review?

Output: no

Input: Consider Input: Review: SPOILERS (ALTHOUGH NONE THAT AREN'T REVEALED IN THE FIRST TWO MINUTES OF THE MOVIE)Robin Williams is actually quite good in this as the friendly, lonely, emotionally stunted loser Sy. He makes a very human, even sympathetic psycho, and really disappears into the character--no small feat for such a recognizable performer. Too bad the rest of the movie is such a waste. The supporting performances (and performers) wouldn't look out of place in a soft-core porno (it doesn't help that every character but Sy is made of 100% cardboard). At times, the director actually seems to be trying to frustrate suspense: we know from the very first moments a) that Sy is a complete whack-job, b) that he survives, and c) that he gets nabbed by the cops at the end. So all we're left to ponder is the hows and the whys, and the answers provided aren't all that interesting.The plot is plodding and contrived, and features some nonsensical moments (for instance, the husband berates his wife for her expensive tastes, even though she seems to spend all her free time at the local discount superstore). About two thirds of the way through, Sy does something so irredeemably stupid that it makes one wonder how much he actually cares about his grand revenge scheme. And the final cliched explanation of his psychosis, right out of 'Peeping Tom,' is a terrible copout.The dialogue is of the absolute worst sort. It's not overwritten, or awkward, or unbelievable, or bad in any other way that could be considered fun, even for bad-movie lovers. Instead, every line is purely, hideously functional--it's as if the director handed a plot outline to a newspaper copywriter and said, 'Hey, I need a workable script on this--in an hour.' It made me want to scream, honestly.This movie seems to be a throwback to the suburban beware-the-help thrillers of the eighties and nineties ('The Hand That Rocks the Cradle,' e.g.), and while it's certainly unpleasant, it's never really scary. Sy's fetishism occasionally makes you feel uncomfortable, but on its own that's not enough to make the film work. In the end, lack of craftsmanship from everyone involved, except Robin Williams, sinks this one. 3 out of 10. Question: is it a positive review?

Output: no

Input: Consider Input: Review: I found it very very difficulty to watch this after the initial 5 minutes of the film. I managed to stomach 45-50 minutes before switching it off in disgust and watching Monster House instead (which, by the way, is great fun).The story has massive holes in it. The plot line is hugely over stated and dull, the acting is awful, especially from Justin TImberlake who should really stick to what he is good at (looking daft and singing like a castrato). Morgan Freeman looked incredibly uncomfortable, especially when made to dance around to rock music for no apparent reason half way through the film after him and Timberlake meet. Freeman and Timberlake's characters seem to be supposed to have some sort of father/son relationship of sorts or something, which simply isn't evident at all apart from the fact that; though Freeman's character seems to have nothing but contempt for the ignorant and rather stupid character of Timberlake, he never the less pulls out all the stops to help him uncover a completely ridiculous cover up.It would take some incredible suspension of disbelief to give any credit to the story line, which is simply absurd and blown out of all proportion.Don't watch this film, it is a pure waste of time.
