Review: Saw a trailer for this on another video, and decided to rent when it came out. Boy, was I disappointed! The story is extremely boring, the acting (aside from Christopher Walken) is bad, and I couldn't care less about the characters, aside from really wanting to see Nora's husband get thrashed. Christopher Walken's role is such a throw-away, what a tease! Question: is it a positive review?

Ex Output:
no

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?

Ex Output:
yes

Review: I am a big fan of old horror movies, and since I am middle aged, old to me is a movie made before 1970 with most being made in the 1920's to 1960's period. I am not a big fan of more modern horror movies, with one exception being Creepshow 1, which I thought was great. I could reminisce about the stories there but I really really enjoyed the monster in the box story with Hal Holbrook, and also the one about the really clean guy was a great ending. All the stories were great though. So why did I like them so much? The characters had some decent development, the lines were very plain about who was good and who was bad, the horror bits were heightened with a close up of a face aghast with fear, and the funny bits were really funny! This sequel is either greatly lacking of these elements or they are totally absent! I am writing this only having watched it partially because the movie was a complete waste of time and I turned it off to do other things like write movie reviews on IMDb.com, lol. When George Kennedy and an old Dorothy Lamoure get top billing it's telling you something.....4 of 10. Also, Romero's expertise is hard to find here, they must had told him to tone it down to a PG standard (I don't know what this was rated at but it looks PG to me), and that's not a good thing for a movie with nothing else going on. It's shown on the Encore cable channel if your dieing (yuck yuck) to see it. Question: is it a negative review?

yes
