Example Input: Review: Most book adaptations are bad but this film left out key parts of the storyline and changed the description and some characters. They rewired the storyline and combined scenes and changed the order. They added ridiculous things into it that never happened in the book and would never happen.If i hadn't read the book beforehand it would have been an incredibly dull film, it didn't make you care about the characters, like them or dislike them. It turns the characters into jokes.Awful.Ridiculous.Waste of two hours of my life. 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: This is my first movie review on IMDb. I was forced to register after watching this movie. I cannot in good conscience allow this movie to be unreviewed by me. The people must be warned!First of all, my rating is: 0 (as in "zero")I love Jack Black, Ben Stiller, Rachel Weis, and Christopher Walken, and yet, I hated this movie. There is a plot, but who cares when there's no script. The dialogue is unreal and plain boring, the situations are contrived, the flow of events is slow and somewhat arbitrary, the characters are unsympathetic and uninteresting, and the story, although based on a good premise, is stupid. This movie is a piece of poo.Never mind wasting MONEY on this movie, it's not even worth your TIME spent watching it. Please do not see it... I beg of you! Question: is it a positive review?
Example Output:
no
