Example Input: Review: If there was a 0 stars rating i would gladly hand it out to this absolutely horrid pile of waste. The fact that the actual summary is perfectly fine and that if it had been made different it could have been brilliant only makes it worse. The basic task of locking up a group of people in an experiment chamber is fine, but WHERES THE EXPERIMENT? All i see is a bunch of unintelligent surfers and blondes chatting about music and culture i don't know or want to know about... The challenges are pathetic and silly. The whole point of reality TV is to show REALITY. If you set a 'challenge' don't make them play with exaggerated props of food and stereotypical cultural elements in 'friday night games'. make them do an actual challenge. And as for 'earning' prize money, thats fine, if they actually earnt it! These people are nuts. If only they would make the show better, the actual idea would be glorious. But that ain't gonna happen! Question: is it a negative review?
Example Output: yes

Example Input: Review: Grand Canyon is a very strange bird. It's a completely unique urban piece, where relating the entire plot would fail to convey much.It's central theme seems to be the inherent uncertainty life holds for people of every race, background and station. But to proclaim that THE theme of the film would be to horribly understate its scope. Similarly, to pigeonhole it in a particular genre is futile.The film has volumes to say, though likely different volumes for every viewer, and says it all in such a non-preachy way from so many angles, that in the end, i can't even define its central message for myself.Nevertheless, it does it's business with such laser precision; every prop, line of dialog, and bar of background music contributing to it's pervasive mood and powerful message, that i'm pleasantly surprised, and come away very thoughtful after every viewing. Still it doesn't feel at all stuffy. A sparkling film with a great cast and everything working. Question: is it a positive review?
Example Output: yes

Example Input: Review: There isn't a whole lot going on in this story -- just two men employing very different ways of handling memories of Vietnam. But what it lacks in premise, it more than makes up for in acting and realism. It's a quiet film about the bonds of friendship and shared experience. We even get romance (not gratuitous -- just another very real piece of this story). It's well worth seeing. Question: is it a negative review?
Example Output:
no
