Example Input: Review: This was a blind buy used DVD. It totally killed a nice buzz I had going when I hit play.It's bubble-headed comedy, but it's um. squalid. The plot is ZANY!, but the characters do things to each other that are so petty and disturbed and conveniently contrived I ultimately found it depressing to watch.Maybe the box lead me to expect something more than an uneven, goofy caper film. (I know, I know, the quotes on the box & the Academy Award nomination mean nothing.) Question: is it a positive review?
Example Output: no

Example Input: Review: I don't hand out ten star ratings easily. A movie really has to impress me, and The Bourne Ultimatum has gone far beyond that. Furthermore, this trilogy has come together so nicely, that I believe it to be one of the greatest motion picture trilogies of our time. Though all three films could not be any more different from the Ludlum novels, they still stand as a powerful landmark in cinematic achievement. The Bourne Ultimatum made me want to cry that the series was complete, yet I could not even attempt to stop smiling for hours.From the moment that the opening title appeared, I knew we were in for a ride. Paul Greengrass has done it again. Everything we love from the previous Bourne films is here once again: the action, the dialogue, and of course the shaky camera. However for me, that last one was never a problem. I think it adds to the suspense.I will be back to see this film several times before it is released on DVD, simply because it is genius. It is a perfectly satisfying conclusion, and should stand the test of time as a fantastic movie, and altogether, an unforgettable trilogy. Question: is it a positive review?
Example Output: yes

Example Input: Review: I only saw IPHIGENIA once, almost 30 years ago, but it has haunted me since.One sequence particularly stays in mind, and could only have been fashioned by a great director, as Michael Cacoyanis undoubtedly is.The context: the weight of history and a mighty army and fleet all lie on King Agamemnon's shoulders. An act of sacrilege has becalmed the seas, endangering his great expedition to Troy. He is told he must sacrifice his daughter Iphigenia to Apollo in order to gain the winds for the sails of the Thousand Ships. He initially resists, but comes around, and tricks his wife Clytemenstra to bring their daughter to the Greek camp in order to marry the greatest of all warriors, Achilles.Clytemnestra and Iphigenia arrive, find out about the sacrifice, and rage to the gods for protection and vengeance. Meanwhile, the proud Achilles discovers that his name has been used in this fraudulent, dishonorable way. He climbs a hill to tell Iphigenia that he will protect her.The shot: The camera circles the two young people, without looking directly at each other. They bemoan their fate, and the weakness of men that deceive their loved ones and lust for war. Suddenly, they gaze at each other and, for one moment, we feel both their power and beauty, and the unstated--except by the camera--irony that in another time, another place, they perhaps could love each other and be married. It is a sharp and sad epiphany that lasts only for an instant.What direction! What camera! What storytelling! Question: is it a negative review?
Example Output:
no
