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: There is good. There is bad. And then their is The Sentinel, a bottom-barrel political "thriller" that ranks among the worst movies I have ever seen. The plot of a mole in the Secret Service is a good one, but never has a movie with so much potential been so utterly butchered. Directed with ham-handed "edginess" by Clark Johnson, every actor in this film seems to be working on autopilot. Even the great Michael Douglas looks bored here. I can honestly say I have NEVER, in all my life, viewed another film with so many glaring plot holes. The twist is predictable from square one, and the character's motives are so utterly ridiculous that they inspired laughter from the audience. Avoid this at all costs. This is a catastrophe of a movie with no redeeming value. Question: is it a positive review?
Example Output: no

Example Input: Review: I attempted to watch this film without being able to really sit through it, for while it is suppose to have a "good" message; the problem is that it is obviously produced according to one particular interpretation of scripture. An interpretation, in my opinion, will mislead a lot of people. In addition, I am a movie maniac and the acting in this film was completely unacceptable. Never before had I wished for a negative score to rate a movie. So, if you wish to be preached to incessantly by those without authority, then by all means, get this film. This comment is also a warning to people who like or love scifi, because the title will deceive a lot of people as well. This was an unfortunate film, because the basic idea had possibilities and those possibilities were squandered. The film's only redeemable quality is that it did make me realize that the character in the "Time Machine" probably should have shown a little more moral outrage at the odd behavior by those in his future. Question: is it a positive review?
Example Output: no

Example Input: Review: Forbidden Siren is based upon the Siren 2 Playstation 2 (so many 2s) game. Like most video game turned movies, I would say the majority don't translate into a different medium really well. And that goes for this one too, painfully.There's a pretty long prologue which explains and sets the premise for the story, and the mysterious island on which a writer (Leo Morimoto) and his children, daughter Yuki (Yui Ichikawa) and son Hideo (Jun Nishiyama) come to move into. The villagers don't look all too friendly, and soon enough, sound advice is given about the siren on the island, to stay indoors once the siren starts wailing.Naturally and slowly, things start to go bump, and our siblings go on a mission beating around the bush to discover exactly what is happening on this unfriendly island with its strange inhabitants. But in truth, you will not bother with what's going on, as folklore and fairy tales get thrown in to convolute the plot even more. What was really pushing it into the realm of bad comedy are its unwittingly ill-placed-out-of-the-norm moments which just drew pitiful giggles at its sheer stupidity, until it's explained much later. It's one thing trying to come up and present something smart, but another thing doing it convincingly and with loopholes covered.Despite it clocking in under 90 minutes - I think it's a horror movie phenomenon to have that as a runtime benchmark - it gives that almost two hour feel with its slow buildup to tell what it wants to. Things begin to pick up toward the last 20 minutes, but it's a classic case of too little too late.What saves the movie is how it changes tack and its revelation at the end. Again this is a common device used to try and elevate a seemingly simple horror movie into something a little bit extra in the hope of wowing an audience. It turned out rather satisfactorily, but leaves a bad aftertaste as you'll feel cheated somewhat. There are two ways a twist will make you feel - it either elevates the movie to a memorable level, or provides you with that hokey feeling. Unfortunately Forbidden Siren belonged more to the latter.The saving grace will be its cinematography with its use of light, shadows and mirrors, but I will be that explicit - it's still not worth the time, so better to avoid this.
