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?
Example Output: yes

Example Input: Review: I've seen my fair share of badly thought-out endings and final twists to films, but I don't recall any film that committed outright suicide like this one did.The film makers were clearly hoping that the great twist would 'surprise' us all.... and it did, but perhaps not in the way the directors had hoped. I was left feeling surprised that Connery, Harris, Fishburn and Capshaw had anything to do with this turkey, individually or collectively.The film up until the final thirty minutes was rather engaging and I like the way the story was unfolding and the nature of the film overall. But once the twist was revealed, the plot holes and inconsistencies were remarkable, the underlying motive for revenge was ill-conceived and the ways things so neatly worked out for Bobby Earl was ridiculously far-fetched. What's worse is that, once the twist was revealed, the remainder of the film became excruciatingly predictable.Harris gave a terrific performance and Connery is like Morgan Freeman in that he never gives a bad performance, even if the movie ain't that great! So all in all, it starts well and the unfolding keeps the viewer interested. The last 30 minutes is one of the most memorable nose dives in the history of cinema. Question: is it a negative review?
