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: The 1986 TV movie of The Spirit was a pilot for a possible series. However, Spirit creator Will Eisner did not like the film and thus no series was produced. I thought it was a very entertaining film and captured the spirit (sorry) of the comic with a modern twist. I'm sorry it didn't materialize into a series. Sam (Flash Gordon) Jones was a perfect Spirit. Nana Visitor was a nice Ellen Dolan and of course would later go on to Star Trek:Deep Space Nine years later. Maybe with the release of Frank Miller's big-screen version of The Spirit, more people will be able to see this rare gem of Spirit history. It seems that when Hollywood makes a film from an already established character or idea, someone will inevitably seek out previous versions of the property and release it to video in order to make a few dollars. When Antonio Banderas donned the mask of Zorro, we were able to get earlier versions of the masked hero on DVD, such as the great Alain Delon version of the 1970s (although all copies I ever saw were badly edited). Heres hoping someone will release the TV adventure of The Spirit to DVD soon. Question: is it a positive review?
Example Output: yes

Example Input: Review: Before starting to watch the show, I've heard it was great and aesthetically very interesting. What a deception, the scripts are so dumb that I am quite sure the authors are son and grandson of Scoobidoo writers. And what about the SFX and colors, they are so extreme that it is painful to watch, colors are not saturated they are over saturated, like scripts are overwritten and show is overrated. This show is like a bad pie in which a child would have put only sugar and butter thinking that because these ingredients are the best, they are sufficient. Unfortunately for this show, the only two ingredients of this show are finally vacuity and a total lack of credibility. Question: is it a negative review?
Example Output:
yes
