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 Input: Review: Alas, poor Hamlet. I knew him, dear reader, and let me tell thee, THIS VERSION SUCKS! I don't know who of all people put up the money for this flotsam, but I hope that they're proud of themselves. They took THE classic play and turned it into the most boring melodrama imaginable. This version is quite literally so bad, that not even the presence of a great thespian like Maximilian Schell in the title role can save it. This movie's only redeeming quality is that it made great fodder for "MST3K"; Mike, Servo and Crow had a lot of fun with this one.But either way, I'm sure that Shakespeare, had he been alive when they made this, would not have wanted his name associated with it. This "Hamlet" is not even so bad that's it good; it's just plain bad. Absolutely dreadful. Question: is it a positive review?
Example Output: no

Example Input: Review: Witty. Quirky. Genuine. Surreal. Butterfly wings? One could ask what all of these words best describe, and some (those in fuse with the international film community) may quickly say Happenstance, but others may jump aboard the more American train and immediately yell, The Butterfly Effect. Strangely, I would be one of those screaming for that sci-fi Kutcher film mainly because none of those words that I initially mentioned at the start of this paragraph accurately depicts the Tautou feature that I witnessed. Sure, we all loved her in Amelie and thought she was the daughter of Jesus in The Da Vinci Code, but in this film first-time director (of a feature film at least) Laurent Firode doesn't give Tautou the opportunity to shine. Sadly, he gives nobody the opportunity to really demonstrate themselves because he is too delicately caught up in the moments of "random chance" to bring this film to anything but just a shimmer (never a true boil). Firode has ample, and I use "ample" as a small word, moments throughout this film where he could have built us a fantastical story, a genuinely whimsical fairy-tale of love and coincidence, but instead he fell face-first into a mud-bucket of chaotic intertwining that overwhelmed us with inconsistent characters and a story that left us gasping for less.Tautou's beautiful face adorns the cover of this box, but do not be so taken immediately as I did in assuming that this was going to be another monumental journey into Tautou's French cinema. Tautou is in this film, do not get me wrong, but one could argue that she is not at the center of this story. Firode's job is to create a series of random events that eventually will lead to an audience friendly (albeit confusing) ending which exemplifies that meaning of refreshing "melodrama". He utterly, utterly fails. Firode fails by giving us, the audience, too many characters. With too many characters he gives us too many random interventions, and by the end you don't really care who is who, or what is what, or how is how; your main focus happens to be centered solely on the ending credits and the time destination of their arrival. Tautou could have saved this film from the disaster it was if only Firode would have given her the center. Alas, he did not, but attempted to seemingly force a group of 12 through a theoretical film hole about the size of a penny. It just didn't work and we were left with a jam in which we were completely stuck.Firode fails because he focus' so intently on the minor details that, for one of those rare film occurrences, he actually forgets the central focus. I can say that there was no defined central focus to Happenstance. In the beginning he attempts to create one with our two supposed main characters discovering that they share the same birthday and their horoscope promises love by the moonlight, but we never go back to that throughout the film. Instead, again, we are bombarded with new characters, stuffy scenes, and meaningless drivel obviously chosen to direct us away from an actual story and more into a world full of "ifs, ands, and buts". I couldn't do it. I couldn't believe this film. Writer Firode (yes, the same guy directing this garbage) uses a technique so primitive in this film that I immediately felt like ending it immediately. He must have been assuming that many of us were incapable of actually following the storyline (or the scientific premise) because he grabs the aid of a homeless person to actually fill in the respective blanks. I didn't need this, nor do I think Firode needed to belittle his audience in this matter. While there were other elements that just didn't seem to work for me at all (again, felt like a jumbled Parisian collage of shredded paper), this was the icing on the cake. I don't need my hand held through films.I will give this film one star for credit. This is a rather difficult genre to master successfully. Time travel films are especially hard because of the innumerable amounts of possibilities that are never accounted for, but with Happenstance it works because Firode semi-explores the different avenues. While I will counter with saying that he does not do it well, it did make for at least five full minutes of enjoyment. I liked where Firode was headed with this film, he had a genuinely diagramed story, but the final execution just blew this film to shreds. Firode could have saved this film if he would have strengthened his characters, while lightening up his premise and story. I think my overall mood of this film would have changed if just these two simple directions were taken. Oh, how I only wish I could time travel back to the production of this film to show Firode the errors of his ways.Overall, for the first time (and probably last), this was a Tautou film that I must say utterly disappointed me. From the choppy opening to the apathetic ending, I just felt that Happenstance failed due to Firode's leadership and horrid marketing. Marketing is something that I didn't mention before, but why would anyone purchase this film thinking that it was an Amelie 2 (per the title released in Hong Kong), and why would you place Tautou squarely on the cover knowing full well that she wasn't carrying this film at all. I believe that from the first minute that passed on my DVD player, this film was in shambles. While I will applaud his subject, everything else was well below the level of mediocrity. I cannot suggest this film to anyone.Grade: * out of ***** Question: is it a positive review?
