Example Input: Review: We purchased this series on DVD because of all of the glowing reviews we had seen here. I gave it three stars because there can be little doubt that sometimes the acting, directing and writing are brilliant. In fact they are so brilliant we did not see the propaganda that was being transmitted so smoothly on the series. If one watches it with discernment, one will see the entire litany of the radical right wing beliefs being promulgated by the Fox (Faux) News Network. To avoid giving away any spoilers I will refrain from pointing out all of the dozens of specific instances. A brief look at the plots found here on IMDb will disclose that everything from torture to gun control to the right of a network to provide "Infomercials" and call them news is justified with cute plot twists and impassioned speeches given by some of the best actors in the world. We watched many shows and finally gave up in disgust when they justified torture using Attorney General Gonzales as a shining example of why all kinds of torture should be used in the name of protecting all of us. The series also manages to demean male and female gays in subtle ways by using them as plot devices depicting evil people. All in all the complete litany of the radical religious right wing.No doubt the popularity of this program will be used by future historians as proof that America lost its way in the early part of the this century. As a student of history myself I would characterize this program as being in a league with the propaganda produced by Goebbels for Hitler and some of the propaganda produced by Hollywood for the American audience during WWII.So if you want to use this as a teaching tool to help your students understand how subtle propaganda can be then by all means do so. Just be sure to purchase an inexpensive used copy so you can avoid enriching the ultra right wingers at Faux Network who produced this travesty. Question: is it a negative review?
Example Output: yes

Example Input: Review: Shamefully, before I saw this film, I was unfamiliar with Helena Bonham Carter.I had to do some research, in order to assure myself she wasn't actually afflicted, as was her character, with (well?), what she was afflicted with. I was in absolute awe of this beautiful lady. She pulled it of flawlessly.Who would have thought that sexually explicit circumstances involving the final wants, and needs, of a unique young lady, could be interpreted as tender, and romantic? Well, they can be, when the right performers present them in the proper manner, as they did in this wonderful movie. I forgot to mention how dynamically beautiful Miss Carter looked in this movie. I have often said she was the most beautiful creature to have ever graced the face of our earth, but she seemed to have out done herself in this particular movie.I hope any of you who watch this movie enjoy it as much as I did. Thank you for letting me express my opinion. Question: is it a positive review?
Example Output: yes

Example Input: Review: Picture the scene where a bunch of scriptwriters sit around a table and one says "lets have a black woman approach an unsuspecting member of the public (also black) in the street and ask him if he is black, then walk away". The other writers fall about laughing hysterically until one suggests they repeat it in every episode. More laughter. Now if you think the premise is funny, and the show contains many such types of situation, you will enjoy this show. For the rest, use your zapper and find something more entertaining like watching paint dry. Those that have written glowing reports of this show should either get out more or be forced to watch television comedies that are really funny. Another example of the humor in the show, a girl tries to get out of paying at a supermarket checkout by trying to hypnotise the cashier. Marginally funny the first time but why repeat it over and over in different shows with different cashiers? I could give other examples but these just might be treated as spoilers, divulging why this comedy just is not funny at all. Question: is it a positive review?
Example Output:
no
