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: I happened upon this film by accident, and really enjoyed. Timothy Busfield's character is without redeeming qualities, and at one point, Busfield and star Meloni ogle women as they pass by...Meloni's take on the parade is different from Busfield's. Janel Maloney is terrific...She looks very much like Tea Leone, but the major difference here is that Janel can actually ACT. Some very nice things in this film and well worth your attention when it's on cable. Question: is it a positive review?
Example Output: yes

Example Input: Review: In my book "Basic Instinct" was a perfect film. It had outstanding acting on the parts of Stone, Douglas and all the supporting actors to the tiniest role. It had marvelous photography, music and the noirest noir script ever. All of it adding up to a film that is as good as it will ever get!This sequel is the exact opposite, it cannot possibly get worse, bad acting and a lame script, combined with totally inept direction, this is really bad, boring, annoying. The only thing that somewhat keeps you concentrated is the relatively short wait for the next scene that is an exact re-enacted copy of the original. These copies are so bad they make you laugh and I laughed a lot in spite of myself, because it was like watching the demolishing of a shining monument. The only thing that is good in this horrible mess are the excerpts of the Jerry Goldsmith score of BI1. Michael Caton-Jones and the half-wit responsible for the script even included the "There is no smoking in this room" dialog in the interrogation scene and yes she sends her attorney (who is now a solicitor) away! I am sorry I have seen this awful film that should have never been made! It does damage to the original, so bad is it. The only redeeming value is the realization that cosmetic surgery (and I am sure Ms Stone afforded the best surgeon money can buy) can do a good job but can obviously not restore the perfection of the original. And what concerns the human body applies to film-making, too. There should be a law: Don't ever make a sequel to a perfect film! Question: is it a negative review?
Example Output: yes

Example Input: Review: Pretty disappointing prequel to the first two films, it's got none of the suspense of the first nor the interest of the second. By concentrating on the guys who 'run' the cube, it basically takes away any of the sense of tension inside the cube, as we simply don't care about the characters inside. Much of the film is simply boring, and it only becomes truly terrible with the introduction of the glass-eyed superior and the green-eyed crazy marine. After that, though, it just descends into over-the-top unintentional hilarity. The ending is fitting though, tying it back into the first one in an indirect way. The script is terrible, the acting mediocre at best, and the direction unimpressive. A much lesser follow-up. Question: is it a negative review?
Example Output:
yes
