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: Simply one of the best ever! Richard Brooks' adaptation of Truman Capote's non-fiction novel is truly an artistic achievement. Stunning black and white cinematography (that should have won an Oscar), a haunting Quincy Jones score and tremendous performances by Robert Blake and Scott Wilson as the oddly-matched killers. This film was 0 for 4 at the Academy Awards and wasn't even nominated for Best Picture while Dr. Doolittle was. Go Figure! Although you don't get to know the Clutter family as well as you do in the book, it was a good decision to focus more on Perry and Dick and the pain-staking process of tracking these guys down. John Forsythe is also impressive as Alvin Dewey. There are simply no flaws in this one. 10 out of 10. Best performance = Scott Wilson with R. Blake a close second. Highly recommended! Question: is it a negative review?
Example Output: no

Example Input: Review: This was a very brief episode that appeared in one of the "Night Gallery" show back in 1971. The episode starred Sue Lyon (of Lolita movie fame) and Joseph Campanella who play a baby sitter and a vampire, respectively. The vampire hires a baby sitter to watch his child (which appears to be some kind of werewolf or monster) while he goes out at night for blood. The baby sitter is totally oblivious to the vampire's appearance when she first sees him and only starts to put two and two together when she notices that he has no reflection in the mirror, has an odd collection of books in the library on the occult, and hears strange noises while the vampire goes to talk to the child. She realizes that the man who hired her may not be what she thought he was originally. She bolts out the door, the vampire comes out looking puzzled and the episode is over. I don't know what purpose it was to make such an abbreviated episode that lasted just 5 minutes. They should just have expanded the earlier episode by those same 5 minutes and skipped this one. A total wasted effort. Question: is it a negative review?
Example Output:
yes
