Example Input: Review: I really didn't like this movie because it didn't really bring across the messages and ideas L'Engle brought out in her novel. We had read the novel in our English class and i absolutely loved it, i'm afraid i can't say the same for the film. There were some serious differences between the novel and the adapted version and it just didn't do any credit to the imaginative genius that is Madeleine L'Engle! This is the reason i gave it such a poor rating. Don't see this movie if you are a big fan of L'Engle's texts because you will be sorely disappointed. However, if you are watching the movie for entertainment purposes (or educational as was my case) then it is an alright movie! Question: is it a negative review?
Example Output: yes

Example Input: Review: in fact,it's basically the same movie.and they couldn't even get the time line of events correct.maybe that was intentional due to laziness or not caring.either way,this thing is a real woofer.it doesn't even deserved to be called a movie.i viewed this as a so called second feature on the disc containing the original The Boogeyman.i thought my head would explode,and i urge you to run as far in the opposite direction of this thing,if you should be cursed with the misfortune of combing across it's path.it should come with a warning label like:Warning-may cause your i.q to drop several points if you are within it's vicinity.for me,there's no doubt this thing is a 0/10 Question: is it a negative review?
Example Output: yes

Example Input: Review: At first look of the plot tagline I figured it could have been a decent film. Could I have ever been more wrong? The beginning of the film makes it look like a bunch of freaks got together and decided to make a low budget film. For the first 10 minutes you don't notice the cheesy acting, horrible sound and god-awful special effects, but then it gets worse. Just about 20 minutes into it I was asking myself, "What was the plot again?" I could only ask that question when I wasn't busted out laughing from the sheer lameness of this film. The main actor has one setting for emotions and he sticks to it throughout the entire film, even though he was supposed to go through love and hate and everything in-between. The flashback scene almost made me vomit because it made me re-live one extra minute of footage from earlier in the movie. Now we hit the middle of the film where they are obviously trying to rip off Morpheus from "The Matrix," although he is doing just a horrible job. The actor's talking about "Star Wars" and fortune cookie phrases is almost unbearable. Now at the end of the movie you don't realize that it's the end of the movie because you actually think the plot is finally developing. The "Morpheus" character dies, the ONLY good thing about the movie. He utters a couple words and the credits roll. What is this? No plot, bad acting, cheesy everything, it couldn't get any worse. Please, if you value human decency, DO NOT WATCH THIS MOVIE! Question: is it a negative review?

yes
