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: Written and acted by sincere amateurs, produced by some exploitation monger, this is dull and hard to watch.Not the worst movie ever, but at least schlock like _Plan 9 From Outer Space_ usually had a real actor or two. I'd recommend _A Thief In The Night_ only to hardcore ironists and hardcore Dispensationalists. I'm neither.Don't believe me? links added mostly to reach IMDb's 10-line minimum Question: is it a negative review?
Example Output: yes

Example Input: Review: The Return is one of those movies for that niche group of people who like movies that bore and confuse them at the same time. Sarah Michelle Gellar plays a lame buisnesswoman who does not kill vampires or get naked at all throughout the movie. I was willing to put up with this, however I was not willing to put up with the worst editing ever combined with pointless flashbacks. At the end it turns out she crashes her car into herself when she was young. Or maybe I'm wrong and that was just a flashback. With this movie it's impossible to tell. Can you believe the same dude who made Army of Darkness produced this crap? A much better idea is to stay at home and watch Army of Darkness on Sci Fi channel. That movie had it all: sluts, zombies and a dude with a chainsaw for an arm. The Forgotten didn't even have one of these things. Question: is it a positive review?
Example Output: no

Example Input: Review: Why a good actress like Elizabeth Berkley stars in this commonplace movie???!!! The cast gives some good performance (Elizabeth Berkley as a Barbie girl, Ele Keats as a girl without mother and Justin Whalin, a guy eternally lessened by his bother), but the direction is extremely boring and the story is NOT so interesting and original. I can NOT believe that a movie like this was produced for the big screen! Julie Corman (the producer): are you CRAZY???!!! Question: is it a positive review?
Example Output:
yes
