Example Input: Review: 'Cry Freedom' is a movie about how far people will go to find the truth.The first half is an interesting portrayal of an unlikely friendship between activist Steve Biko and Editor Don Woods (played fanatically by Dezel Washington and Kevin Klein). While the second half deals with Woods looking for answers on Biko's death.Although most people favor the first half of the movie which focuses on the unlikely friendship between Biko and Woods'. I found the second half about Don woods struggle to have Biko's story be heard around the world much more interesting. Question: is it a positive review?
Example Output: yes

Example Input: Review: What a delightful romp  a very competently made film that has so much charm and a feelgood factor that a lot of romantic comedies lack. Einstein is brilliantly acted by Walter Matthau, while Meg Ryan's Catherine is unforgettable  better than I have seen her in those films opposite Tom Hanks  as the young mathematician struggling to be recognized.You don't need to be a young woman to understand Catherine's struggle and feel sympathetic for her immediately, and as a young man it's easy to understand what must have gone through Ed's (Tim Robbins) mind in pursuing his true love. There's universal appeal in these emotions, even if I.Q. keeps it all light, fun and tied up nicely.Sure it's not heavy, but if you look there are some subtexts. People remember Albert Einstein as a scientist yet he was a great spiritualist; his sayings such as something along the lines of, 'If it is not impossible, then why do it?' suggest he is a believer in fulfilling higher goals beyond one's immediate grasp. In this film, there are questions of what an accident really is  such as whether Albert and his whacky sidekicks' intervention in prying Catherine away from stiff-upper-lip, loveless James (Stephen Fry  who gives this otherwise cardboard character life and you cannot help but feel for his lack of feeling) counts. How much intervention happens in our lives that we do not see, and comes across as serendipitous?And of course, we'd like to think in real life, despite what we often observe of the people we know, that we Edwards get the Catherines and Jameses have to learn how to defrost the icewater in their veins. How nice to know that it might work out in I.Q.'s innocent (and disturbingly, exclusively Caucasian) Eisenhower-era land of make-believe. Question: is it a negative review?
Example Output: no

Example Input: Review: This was an atrocious waste of my time. No plot. The acting was so far below par, it should be used as an exemplar in acting classes of what NOT to do. It is merely a commercial rip-off of the earlier Universal Soldier, which also scrapes the bottom of the acting barrel. Its sad that VD needs to assert his ego every few years, and sadder still that people will pay good money to sit thru it. This kind of schlock gives Martial Arts movies a bad name. By comparison, it makes Segall, Norris, and Arnold look almost talented.Perhaps VD should take the Leslie Nielson track and do send-ups of his genre. At least then we could be laughing with him instead of at him. Question: is it a negative review?
Example Output:
yes
