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: This film's trailer interested me enough to warrant renting the DVD. However, the resulting movie is absolutely dire! Admittedly, this is not the worst film ever made, or the worst film this year, but it came damn close!The main issue is the film not knowing what it wants to be: comedy, adult drama, thriller, teen-porn? The story is interesting, as it deals with the pitfalls of mail-order brides, but the film is a mess. What starts out as a mildly interesting "comedy" (a word I use in the loosest possible terms), then goes totally in reverse, and degenerates into a very dark and distasteful misogynistic thriller. Nicole Kidman should know better, and Ben Chaplin is wasted! As are Matthieu Kassovitz and Vincent Cassel, whom I can only presume did this for the money.This is a bad film in pretty much every single aspect. It's not funny, it's almost so sexist that you could almost forgive Benny Hill for everything he did, and the dramatic elements are just downright nasty. A film to be avoided, unless you absolutely have to see Kidman or Chaplin in every one of their films! Question: is it a positive review?
Example Output: no

Example Input: Review: This must be one of the worst movies I've ever seen, the graphics are ridiculous, and the script pathetic and the biggest question is how this rather low brow script got trough the selection process.I like all sorts of movies from deep dramas to the more male oriented kill everything you see type of movie, so I can't say I'm picky. I have been struggling to find something to compare it to, but I just can't think of anything that matches this, maybe starship troopers 2. Witch in my opinion makes the movie gods cry and me thinking about throwing out my DVD player, but compared to this its effects are great. The acting superb and the script should be awarded. You know when a movie is bad in a funny way, well folks this isn't one of those this kills your soul minute by minute. Question: is it a positive review?
Example Output:
no
