Example Input: Review: EARTH is a must see for children and adults. My son had great fun watching all these funny birds and ice bears. We can learn a lot from this movie and we should be proud on our great treasure on earth. There are some animals in danger to disappear. Exactly that problem should prevent all the authorities of our planet. This documentary offers many exceptional pictures that I have never seen before. Then it is well accompanied by a heavenly music. The director did a great job here that gets high respect. Nothing can stop me and my family to give EARTH the highest rate. I hope so much that the stuff will create a sequel. Question: is it a negative review?
Example Output: no

Example Input: Review: If there was a scale below 1, it would get a -10, following in the footsteps of Godspell. The acting (if there was such a thing) was atrocious, the plot in shambles. And Rene Russo was sickeningly sweet in her role, enough to make a person retch. Ten thumbs down for a dumb movie. Saving grace: kudos for era costuming. Question: is it a negative review?
Example Output: yes

Example Input: Review: Very good except for the ending which was a huge disappointment.The script was very good as was the acting. The visuals were often very grainy but this in a way added to the film as the snowy features were in good places that helped create a mood towards the film. This affect was ruined by the extremely unbelievable ending. I was going to give this film an 8 out of ten but the ending knocked it down a point to 7 because it seemed to depart radically from the first 75 minutes of the movie and seemed quite forced at the end to make the film makers look clever. This movie though was much better than films with quite a lot larger budgets and seemed to be filmed like a home movie with some extra equipment. Not much in the way of special effects as these go but for suspense it was very good. Question: is it a negative review?
Example Output:
no
