Example Input: Review: I never understood why some people dislike Bollywood films: they've got charismatic actors, great dance numbers, and heightened emotion--what's not to like? What I didn't realize was that I had only seen the upper-crust of Bollywood. Then I watched "Garam Masala". I could tell from the first scene that this was not a movie I was going to like (the film opens with a montage of the two leads driving around a city and apparently happening serendipitously on a series of photo setups populated with gyrating models), but I kept hoping things would improve. Sadly, they didn't. The main problem is that the two protagonists, Mac & Sam, are completely unsympathetic. They spend the entire movie lying to women--and lying brutally- -in order to get them into bed, and the audience is supposed to find this funny, and be charmed. The boys are unscrupulous and inept, and not in a lovable way. Mac even goes so far as to have one of the women drugged in order to keep her from discovering his cheating. The script is extremely poor, with repetitive scenes, setups that never lead to anything, and illogical actions and statements by the characters. In fact, the characters are never really developed at all. The males are boorish, greedy jerks, and the women merely interchangeably beautiful. If you go by this movie, you would think that "air hostesses" are pretty easy to pass from man to man. In reality, betrayal is not so humorous. The only bright spots I found in the movie were one dance number that had brilliant sets, and a few slapsticky moments involving the French-farce, door-slamming aspects of the story. But Bollywood dancing is better enjoyed in movies choreographed by Farah Khan, and for slapstick you might as well just go straight to the silent comedies of Buster Keaton and Harold Lloyd, who seem to have influenced writer/director Priyadarshan not a little. Priyadarshan also takes false credit for inventing the story: the basic premise of the plot is stolen from the 1960 play "Boeing Boeing." The original author of that work, Marc Camoletti, is credited nowhere. At least Priyadarshan changed the title for this remake, rather than brazenly using the original without giving credit, as he did in his 1985 version of this same tale. (According to IMDb's credits list.) Question: is it a positive review?
Example Output: no

Example Input: Review: EARTH is a must see for children and adults. My son had great fun watching all these funny birds and ice bears. We can learn a lot from this movie and we should be proud on our great treasure on earth. There are some animals in danger to disappear. Exactly that problem should prevent all the authorities of our planet. This documentary offers many exceptional pictures that I have never seen before. Then it is well accompanied by a heavenly music. The director did a great job here that gets high respect. Nothing can stop me and my family to give EARTH the highest rate. I hope so much that the stuff will create a sequel. Question: is it a negative review?
Example Output: no

Example Input: Review: There is only one use for a film such as Bulletproof: it reminds you just how bad bad can be. We often see films which we describe as "pretty awful" or "not much good", but then you come across a film like this and you can see that although all those other films aren't "good" they are no way as stinkingly bad as Bulletproof. This was a birthday gift from someone who spent less than two seconds rummaging thru' the DVD bargain bin at our local superstore to fulfil an obligation (i.e. to give me a present). It could have been a serendipitous find but it wasn't: this is so utterly cliched, so badly written, so poorly directed, so badly acted that I'm surprised everyone involved hasn't been arrested and sent down for 10 years. God, it's awful. I suspected as much from about 30 seconds in, but carried on because sometimes - sometimes - bad films are so bad they can be enjoyable. This isn't one of them. It is simply bad. I stopped watching after 45 minutes, and tomorrow I shall throw it in the bin. Question: is it a negative review?
Example Output:
yes
