Example Input: Review: ****Don't read this review if you want the shocking conclusion of "The Crater Lake Monster" to be a total surprise****A claymation plesiosaur rises from the depths of Crater Lake to wreak havoc on a group of local rednecks, not to mention your fast forward button. To call "The Crater Lake Monster" amateurish is to overstate the obvious. If you aren't a fan of low budget drive-in films, you probably wouldn't be looking here in the first place.The problem with the movie is that when there's no monster action going on, it really sucks and goes nowhere. The script is very Ed Wood-ish, in that it's utterly contrived in the way it sets up the main action sequences. Nothing is too outlandish for "The Crater Lake Monster". It explains its dinosaur by having a meteor crash into Crater Lake, 'superheating' the water to the point where it incubates a dinosaur egg that has apparently been resting at the bottom of the lake for millennia. Even if we could accept that the egg could have been lying there for so long and remained uncovered and viable, wouldn't "superheating" the water to such a high temperature cause most of the lake to evaporate? Other than some token fog in one or two scenes, we see no evidence of the water being hot, other than a few lines in the script.The script is padded rather obviously in a few sequences, and it will do anything to get the characters near the lake so that they can be menaced by the claymation dino. A couple just passing through experiences car trouble and while their automobile is being serviced, they decide to rent a boat and head out into Crater Lake. Hmmmm...do you think these strangers in the story could be there so they would run into our title monstrosity? In a sequence that's just plain bizarre, a drunk robs a liquor store and decides to murder the cashier and a bystander instead of paying four dollars for a bottle of booze. A car chase ensues, and wouldn't ya know it...they end up right by the lake. Snack time for Cratey! Yeah, it's not hard to figure out, and you're so far ahead of the script that you're irritated when it takes another ten minutes for these scenes to unfold.The shamelessness of it all is endearing, and I really want to like "The Crater Lake Monster". I just can't do it. There's not enough here to go on, and this is more of a movie to put on during a party, because you could talk right over it and it wouldn't matter. The film has a slim list of the things going for it, the most important being the dinosaur itself, which appears in three forms: a shadow puppet, a large model head that is dragged woodenly through the water, and a fully realized claymation insert that actually looks pretty good. There are also a pair of lovable hicks in it, and they carry the majority of the intentional humor in the movie. A downbeat ending leaves us mourning the death of both the monster AND one of our beloved hicks, so every good thing about this film is dead by the end of it. Why was I so affected by this conclusion? Was it the mournful song played over the closing credits? Or was I just weeping inwardly for the time that I waste watching films like this? Question: is it a positive review?
Example Output: no

Example Input: Review: I am guessing the reason this movie did so well at the box office is of course Eddie Murphy. I think this was his first movie since "Beverly Hills Cop" so at the time he was hot. Considering that one made over two hundred million and it was R and this one made about 80 million and it was pg does say it was not all that popular. I have never been a big Eddie Murphy fan, so that is probably another reason I didn't care for it much at all. This one has Eddie as some sort of finder of lost kids. He must find the golden child or the world is in terrible peril. The plot is very bad, but as bad as it is it does not compare to the special effects. I had seen better stuff done in the 70's than some of the stuff this one offers, Ray Harryhausen did better stuff. Still the main reason you see a movie like this is because of Eddie, unfortunately he is not very funny in this one at all and it just seems stupid to put him in the "Raiders of the Lost Ark" type scenes. I guess they were hoping for a fish out of water effect, but to me it just did not work. Question: is it a negative review?
Example Output: yes

Example Input: Review: I couldn't watch more than 14 minutes of it. It's a GREAT combination of really bad acting and really bad directing. The shots used are disgusting, they broke the 180 degrees angle all the time. My head hurts try to watch that load of "you know what". Dirt on the "mystery machine" window make you see light from the lighting on the windows...annoying. What else... it's so badly framed all the time it's just make you want to scream at that lady directing there. I only directed short films, but I'm pretty sure I'd be way better than that directing a feature film.... the story is unbelievable, just the long french kissing scene at the beginning tell you that it's gonna be pretty awful. So pretty much, try to avoid this really bad movies at all cost, it'll save you the 5 bucks or so for the rental, and that 1h30 hour of your life you'll never get back...
