In this task, you are given a review of a movie and a boolean question whether this review has positive sentiment or negative sentiment. Your task is to generate answer "yes" when the tweet has that particular sentiment, otherwise generate answer "no".

Example Input: Review: It's about time we see a movie that stays unbiased towards these old Indian traditions. At times it is clear how most of the 'doctors' are charlatans, even lying about how they don't charge their clients. While they are wearing their gold watches, the 'donation' box is mandatory. Notice that there are only a couple of people who get 'cured' while we see quite a few cases.Keep in mind while watching that ingesting mercury is not toxic and that the smallest Indian bank note is 5 rupee, while the average salary in India is 1,700 ru/month. Question: is it a positive review?
Example Output: no

Example Input: Review: When you go at an open air cinema under the Greek summer night you usually don't care what the movie is! Edison started really good with some good effort from the singers-who-want-to-be actors and a once again great Morgan Freeman but... (In a movie there is usually a good start to catch audience,done, a bit boring yet story filling middle of the movie that is more about characters and less about action ,done, and the third part is something really good so that you can remember the movie...) when you see 30 elite police officers (packed with weapons that can demolish a building) shoot at a guy behind a car, fail to hit him even once while he kills all (but 3) and then the guy takes out a flame thrower (to kill the rest 3) ,you realise that the Greek summer sky filled with stars is way too good to be distracted by a movie like this! Question: is it a negative review?
Example Output: yes

Example Input: Review: Kalifornia is a movie about lost ideals. A journey on the darkest road ever. The road of no return. The plot is about a couple that set out to find a better life in California. The man (David Duchovny in his best role up to now) wants to write a book about the famous crimes that have happened in America and his girl - who is a photographer - is going to take the pictures. So they set out on a trail of famous murders not knowing what awaits them on the way. To share the journey expenses they decide to find another couple and they put an ad. But the couple that answers it is not just ANY couple. It is one of the strangest couples ever. The girl is a naive, frail creature that dreams a lot and loves cactuses. The man is exactly the opposite. A cruel ruthless murderer. We learn that early in the film and we follow him along the journey to Kalifornia (not with C as usual, but with K, presumably symbolizing the word killer), along his journey of betrayal, murder and finally defeat. All the leads, Duchovny, Pitt, Lewis and Forbes give really good performances and you have to take into consideration that when this movie was filmed not even one of them was a star. The photography is amazing, with darkness covering the greatest parts of the movie, and the music suits the dark character of the film. On the whole this is a really good movie. Don't miss it. You'll think again before taking some stranger in your car to share the gas with! Question: is it a positive review?

yes
