Example Input: Review: Hamlet is by far my favorite of all of Shakespeare's works. Branaugh is one heck of an actor. His portrayal of this was just amazing. His soliloquies were breathtaking. For as long as it was it is rare for a film to hold my interest, however I was engrossed in this particular piece. I recommend this to anyone both fan of Shakespeare and those not so much. This has everything the modern world looks for in its films: murder, betrayal, and deceit. Not to knock Mel Gibson's version, but Branaughs touches the whole work. This leaves no stone unturned. When you finish the film it will feel as if you read the play yourself. Um how you say "two thumbs up". Question: is it a negative review?
Example Output: no

Example Input: Review: James Dickey is a wonderfully descriptive author. When one reads "Deliverance", one is instantly transported into the lush backwoods of the Deep South. When one watches John Boorman's film version of the book, one realizes just how accurately he captures the essence of the book. The camera is as descriptive as the narration. The characters are fully realized, and the portrayals are fantastic. I first saw this movie in 1992, after my freshman year of college. I was in a phase where I was watching movies that were all released within a couple of years of my birth in 1973. Among them were "Patton", "Papillon", and "All the President's Men"; fine films, all of them. This one was easily the class of the group. That says a lot. Question: is it a negative review?
Example Output: no

Example Input: Review: I had no background knowledge of this movie before I bought it, but it sounded cool and I've been wanting to see a really kick-butt Viking movie for awhile now... alas, this film was not what I was looking for. I had hoped for the best, but instead, was delivered a boring Nordic soap-opera that seemed to drag on too long despite its 84 minute running time. The film's premise is intriguing enough: It's about a Viking warlord who defies his God and Odin is so enraged that he curses the warlord's son, named Barek, to death and rebirth as a Berserker. This Barek guy is then forced to live enraged, insane, and violent lifetime after lifetime. The movie is filmed competently enough, with some rich cinematography and quasi-good performances by the actors, but again, I found myself bored and questioning when this dribble would end. The filmmakers had a chance to make something rather entertaining and semi-unique but they dropped the ball. Perhaps it could've been improved with some cheap exploitation tactics thrown in such as gratuitous nudity and lots of gore... I mean, we are talking about "Berserkers" here, aren't we? Vikings were supposed to be BAD enough, what with all the raping and pillaging, so aren't Berserkers supposed to be even more extreme? All in all, unless you're a fan of The Young and Restless (etc...) or, are yourself, in fact, an insane Berserker who likes self torture, I'd probably steer clear of this drab piece of celluloid.
