Example Input: Review: I had to register for IMDb just to post a comment on just how awful this movie is...my cats and a ball of string have a better storyline than this. Not the worst acting I've ever seen, but when you wipe out almost the entire cast of the movie within 5 minutes, it leaves a bit to be desired. There wasn't a single 'scare' moment in the movie, with the exception of when they were watching the movie 'Halloween' on the TV. All around, it seems like it could've been a good story, rolling the credits and saying that Chasey Lain was in it was a bit of a loss as I didn't recognize her right away and her scene was already over before I could've said 'oh yeah, there she is'. I'm so glad I saw this in a hotel and didn't pay for it as I'd be real ticked if I had payed a cent to see this. I normally like or can at least find a redeeming factor in a movie, but this one is an exception. It's so bad that it's not even that amusing so-good-it's-bad....it's just plain bad. Question: is it a negative review?
Example Output: yes

Example Input: Review: This is by far one of my favorite of the American Pie Spin offs mainly because in most of the others the main character (one of the young Stiflers) always seems unrealistic in nature. For example AP: The Naked Mile. You have a teenage guy surrounded by naked college chicks , and has one in particular hot on his trail to rid him of his virginity "problem" and he ends up stopping mid-deed and rides a horse back to sleep with his girlfriend, who keep in mind gave him a "guilt free pass" for the weekend. I can appreciate the romantic aspect of the whole thing but let's be realistic; most people who are watching these movies aren't particularly searching for a romantic story.Whereas the most recent installment finally seems to realize who the audience is and good old Erik Stifler seems to wake up and smell the roses and as always Mr. Levenstein lends his "perfectly natural" eyebrow humor to the equation and scored a touchdown with this new movie. Question: is it a positive review?
Example Output: yes

Example Input: Review: The title of this film nearly put me off watching it. Not being a Manchester United fan, the mere mention of Beckham was a bit off putting, however I put my prejudices behind me and I'm glad I did.I wasn't expecting much of a film, but I was pleasantly surprised. The film sped along with me never looking at my watch and I enjoyed every second of the film. If you liked East is East then you'll love this film. OK so the storyline is nothing new, and the classic storylines are contained within the film but it's all done very funnily, and with a breath of fresh air. The film moves very fast and keeps the audiance entertained. The occaisional funny moments are a good chuckle and not some poor attempt at humour, and best of all it's a good british comedy.

yes
