In this task, you are given a review of a movie and a boolean question whether this review has positive sentiment or negative sentiment. Your task is to generate answer "yes" when the tweet has that particular sentiment, otherwise generate answer "no".

Example Input: Review: James Stewart and Margaret Sullavan play co-workers in a Budapest gift shop who don't really like each other, not knowing they're really sweetheart pen pals who have yet to meet.A very charming romantic comedy, very engagingly played by it's two likable stars and a very eager-to-please supporting cast. The story is well written and the film has that romantic innocence (don't quite know how to explain it) that films today just don't have. This can obviously be compared to the recent You've Got Mail, and the original wins in every way.This is mandatory viewing each Christmas, I can't think of a better way to jumpstart a Christmas feel than this little gem. Question: is it a positive review?
Example Output: yes

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: "Black Angel" is minor whodunit, with June Vincent as a woman trying to save her husband from the electric chair after he is found guilty of killing an old acquaintance. Dan Duryea (the husband of the murdered woman) decides to help Vincent find the real culprit. Peter Lorre has one thankless role as a suspect. This film noir looks and plays like a cheap programmer, never achieving anything special. It is pleasant enough but then, at some point, it stops making sense and the solution to the mystery provokes one of those big "give me a break" reactions. That ending alone could have sank the film completely, but what precedes the conclusion is not very good either. Vincent is a wimpy heroine and Duryea was never very good at playing good guys. I love film noirs, but this one was a real disappointment. Question: is it a positive review?

no
