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: This is the Neil Simon piece of work that got a lot of praises! "The Odd Couple" is a one of a kind gem that lingers within. You got Felix Ungar(Jack Lemmon); a hypochondriac, fussy neat-freak, and a big thorn in the side of his roommate, Oscar Madison(Walter Matthau); a total slob. These men have great jobs though. Felix is a news writer, and Oscar is a sports writer. Both of these men are divorced, Felix's wife is nearby, while Oscar's is on the other side of the U.S. (The West Coast). Well, what can you say? Two men living in one roof together without driving each other crazy, is impossible as well as improbable. It's a whole lot of laughs and a whole lot of fun. I liked the part where when those two British neighbors that speak to both gentlemen, and after Oscar kicked out Felix, he gets lucky and lives with them when he refused to have dinner with them the night earlier. It's about time that Felix needed to lighten up. I guess all neat-freaks neat to lighten up. They can be fussy, yet they should be patient as well. A very fun movie, and a nuevo classic. Neil Simon's "The Odd Couple" is a must see classic movie. 5 STARS! Question: is it a positive review?
Example Output: yes

Example Input: Review: Yes, I know I'm one of the few people longing to trample this movie into the dust of oblivion.So let me me tell you why I feel this way. In truth,had it been advertized as a Zombie film or the like,I might have enjoyed it.But right now,I'm totally speechless.*SPOILER...Though I'm not sure what's to spoil* Let's start with the first HUGE flaw. If I did not know that the movie is called "Darkness - The VAMPIRE Version" and had I not seen some sequences where some individuals seem to be sucking blood, I would not have seen the connection with Vampires. I mean, FANGLESS???? Give me a break!!!Second bad point: what's with the Metal? It appears that all young people, but mainly those so-called "vampires", are into various kinds of Metal,judging mainly by their shirts! Don't get me wrong, I've been into the more extreme forms of music for almost 15 years, but nobody 's going to scare me by showing me some ridiculous teenagers in Iron Maiden (of all bands!!!) T-shirts running around,pretending to be Vampires! "Pathetic" is the only only word that I could use here.Third weakness: the actors. Wait a minute. WHAT actors?! You mean the director's wooden friends! Words would be a waste here.Yes, alright, the movie is very gory, but what difference does that make? It WOULD have been a strong point and something to enjoy if the "briliant" director had not chosen to create an ARTIFICIAL vampire topic in this movie. I wanted to see Vampires,but was treated to some stupid looking kids I would have loved to use my baseball bat on. The Film-makers should simply have advertized the movie saying "cheap B-grade horror with no plot but a lot of gore" !!!This movie is blasphemy against the whole concept of Vampirism. And it makes me sick. Question: is it a negative review?

yes
