Example Input: Review: The Williams family live on a ranch located in the middle of the remote desert. They find themselves in considerable peril when the place is suddenly thrust into a time vortex where the past, present and future collide in a wildly chaotic and unpredictable manner. Director John "Bud" Cardos begins the film on a compellingly mysterious note and gradually allows things to get stranger, crazier and more exciting as the loopy story unfolds. Moreover, Cardos fills the screen with plenty of dazzling visuals and does a nice job of creating a genuine sense of awe and wonder. The admirably sincere acting from a game cast qualifies as another major plus: Jim Davis as hearty patriarch Grant Williams, Dorothy Malone as his cheery wife Ana, Christopher Mitchum as the concerned Richard, Marcy Lafferty as his lovely wife Beth, Natasha Ryan as sweet little girl Jenny, and Scott C. Kolden as the gutsy Steve. The funky special effects offer an inspired combo of gnarly miniatures, neat stop-motion animation monsters (said creatures include a tiny spindly hairless guy, a big, lumpy, fanged beast, and a scrawny lizard dude), and nifty matte paintings. Richard Band's rousing full-bore orchestral score really hits the stirring spot. John Arthur Morrill's crisp, sunny cinematography likewise does the trick. A fun flick. Question: is it a negative review?
Example Output: no

Example Input: 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?
