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: In this little film we have some great characters but a very shallow plot. It is actually nice to watch because Singleton does a great job at presenting the esoteric conflicts and the interpersonal relationships. This makes the viewer forget the nonexistent realism that this movie supposedly is for. In fact what we have here is all the possible cliches and stereotypes put on celluloid in a rate higher than that of a soap. Definitely not a deep movie (even if it wants to be), but better than an average college movie. Question: is it a positive review?
Example Output: yes

Example Input: Review: Young beautiful Eva (Hedy Lamarr) marries an older man (Zvonimir Rogoz). Unfortunately he can't satisfy her sexually and ignores her. Frustrated she goes home and plans to get a divorce. Then, one day, she's skinny dipping in a lake in the middle of the woods. Her horse gallops off with her clothes...and she runs after it! She meets young and very handsome Adam (Aribert Mog). They make love and she realizes this is the man she wants.ENDING SPOILER!!!! Naturally, since this was made in 1933, she has to be punished for her sin so it leads to a tragic finale. END OF ENDING SPOILER!!!!This horrified people in 1933 but it's pretty tame by today's standards. Lamarr's nude swim shows nothing and when she runs after the horse totally nude, it's either shown in extreme long shot or is covered by branches and such. There's only a few minor shots of her breasts. Also when she has sex with Mog, nothing is shown but her face but you see her achieving an orgasm. These scene were considered pretty extreme in their day and were cut out completely of the American release. Now today they're back in. This film would get by with a PG-13 easily now.Shock episodes aside this is just OK. It is beautifully filmed and there's next to no dialogue. Except for the music score this could be a silent picture. Luckily all the actors are good--Lamarr and Mog especially and they're so attractive that they just take your breath away watching them. Also the sequence where they make love is easily one of the most beautifully shot and acted sequences I've ever seen in a movie. The scenes with the sexual symbolism (there's quite a few of them) are unfortunately pretty obvious today. I actually started to giggle during one!So, great direction, beautiful imagery, attractive actors, good acting all around--but I wasn't exactly bowled over by it. I found the movie slow-moving (beautiful imagery does not make a picture for me), somewhat dull, obvious, static and had a negative ending. I can live with the ending but it doesn't excuse the other problems I had with it. Also the final sequence is REALLY strange--and out of place. So I admire this film more than anything else. It was well-done and I'd recommend it but with caution. Many people seem to love this movie so I'm in the minority. Use your own judgment. Question: is it a positive review?
Example Output: yes

Example Input: Review: So...we get so see added footage of Brando...interesting but not exactly Oscar worthy stuff. Susannah York was hardly a slouch. New scene where Lois finds out Clark is Superman is slightly unbelievable in that he doesn't notice that there are blanks coming out of the gun instead of real bullets. Real bullets would have penetrated his clothes and then bounced off him onto the floor but forget that...let's listen to Donner make fun of Lester's version that made more logical sense. The president talks of the Zod "defacing" the Washington monument when it was originally Mount Rushmore. Tweaking that scene made that line quite absurd. Superman's "freedom of the press" line sounded silly compared to "..Care to step outside" which was delivered better and had a fitting connection to Clark's earlier scene in the truck stop. Then there is the ending with the "turn back the world to go back in time" effect. It turned back everything in the whole movie and made you wonder where exactly the rocket aimed for Hackensack, N.J. ever went since it doesn't free Zod and company any more.
