[Q]: Review: While originally reluctant to jump on the bandwagon of watching "Lost", I accidentally caught one episode at the beginning of season 1the one with the polar-bearand it has had my undivided attention ever since. The show, that is. Not the polar bear. So bear (heh) with me while I throw out as much rambling, semi-coherent praise as I can muster."Lost" takes a simple idea of a passenger flight full of people crashing onto a desert island, and gradually adds extraordinary depth to its premise by exploring each character deeply and unflinchinglywhat drives them, who are they? Where did they come from? It soon becomes clear that the island upon which they are stranded acts as a common denominator for many things in their lives, whether they're running away from something (Sawyer and Kate among others) or getting in touch with spirituality (Locke, Claire). But "Lost" also zooms in on the island itself and the mysterious horrors that it houses... and they all seem to be strangely connected.While television actors are not exactly known for their subtlety or dazzling acting abilities, most of the cast of "Lost" are, in truth, spectacular actors for their respective parts, projecting heart and humour in their performances. There's also a multitude of eyecandy, but not generally of the plastic Hollywood kind as most TV shows. The characters all feel very real and they are extremely compelling to watch. Their interactions rarely fall prey to predictable sappiness, petty arguments or cheesy melodrama (although they are annoyingly secretive)  these people are first and foremost trying to survive and whatever relationship appears is treated secondary to action. The realism of these characters facilitate an already well-sculptured plot. About this plot... Imagine a tree as the template plot, then the branches as subplots (in this case, one branch for every character)  well, Lost adds twigs to each branch and then tiny twigs to those twigs as other story lines. If you're a brother/sister to one of the main characters in the flashbacks, you will get your own storyline. If you're a DOG you will have your own storyline. Unless the writers manage to weave them all together into some glorious culmination in the end, they are setting themselves up. I am more than a little worried there will be some disappointing cop-out to this show, as I'm sure most people are.But assuming the writers do pull this off, "Lost" is possibly the best show ever to hit television.9/10 Question: is it a positive review?
[A]: yes


[Q]: Review: From the blocky digitised footage to the acting that makes Keanu "I'm so wooden I could be a Plank me" Reeves look like an Oscar winner this film bites (pun not intended). The best thing about it is the box of eRATicate in the 2nd segment (which out of the three seemed to be the strongest piece in terms of storyline and 'twist'). Wish I'd spent the £3.99 it cost me on something else, like erm.... Natural Born Killers: Directors Cut. If you do buy this, you're really in for a disappointment, do yourself a favour and avoid it like the plague. If you're looking for something amateurish and with actors that are more wooden than a 2x4 then go ahead. However if you want some quality werewolf action look elsewhere, like Dog Soldiers, Wolfen, Romasanta:The werewolf Hunt. Question: is it a negative review?
[A]: yes


[Q]: Review: The movie's premise is spooky: a woman gets pregnant when kissed by a stranger in a bar.But as soon as the movie begins, a horrible opening scene establishes that this is a C type Sci-Fi TV movie. It's a big Star Trek and a bit X-files, but more than anything else it's boring.When the movie kicks into action everything is predictable and cliche. It looked more like a 2 parter in a bad Sci-Fi TV series. No suspense and no thrills, but not for a lack of trying. Just a lot of predictable dramatic conflicts between the main characters.Don't waste your time. Question: is it a positive review?
[A]:
no
