Example Input: Review: I saw this film with a special screening of the work of Owen Alik Shahadah. It is so interesting where did this guy come from. Now he is probably the key independent African filmmaker in the world. And I am not talking about black filmmakers I am talking about filmmakers who are rooted in culture. The idea if anything testifies to the diversity and range of African themes, with his film 500 Years Later it is a African issue. But the Idea doesn't fit that mold. Showing the artistic diversity. The film is an all African cast but the topic is a human topic which most of us could relate to. I just love the mild comedy in it. And the Kora of Tunde Jegede is just amazing, it is really a art-house gem. Question: is it a positive review?
Example Output: yes

Example Input: Review: Who would've imagined -- Hal Hartley creates a filmic corollary to Syriana while retaining his signature idiosyncratic style. The fusion is highly entertaining.Having not seen a Hal Hartley film for about a decade, I approached this one with some caution. His brilliant productions of the nineties had impressed critics and audiences with their unique style and dialog. The director's earlier films featured colorful characters and offered close observations of life -- often in the region of Long Island, New York or in New York City itself -- that were offbeat and insightful.My initial caution stemmed from the description of this movie as a "spy thriller". To my pleasant surprise, Hartley manages to mesh his well established style and focus to produce a highly original drama of international intrigue. It works in more ways than one might imagine. Hartley's film retains the dialog and character focus that are his trademarks, along with a singular cinematographic style.Moreover it is highly appropriate given the current situation in the world and the state of war that has been fostered by dark elements on all sides. Hartley has brought all his skills to something new -- a political film worthy of being mentioned in the same breath as Syriana. Truly he is coming into his own. The cast does a fine job of interpreting Hartley's vision and style. Fans of Parker Posey will see her in full bloom here, still with us and more ripe and gorgeous than before. Question: is it a negative review?
Example Output: no

Example Input: Review: I work with children from 0  6 years old and they all love the Doodlebops. The Doodlebops are energetic, vibrant and appealing. Once they start singing, ''We're the Doodlebops We're the Doodlebops We're the Doodlebops Oh yeah Come and join the fun because we're laughing and we're singing all day" it is almost impossible not to join them in song. The Doodlebops brings the viewer into a world of color and fun. Each show is an adventure, the Doodlebops do not try to change the world with preachy messages all they do is have fun while sorting out everyday life challenges that the young child may relate to. The Doodlebops is an refreshing, high action alternative to regular children's television programs. Question: is it a positive review?
Example Output:
yes
