Example Input: Review: The third installment of the "Carnosaur" trilogy features a bunch of Keystone Kops-quality military commandos trying to kill two Velociraptors and a T-Rex. I give it a 4 out of sheer sympathy and my affinity for dinosaurs. The movie is definitely the worst of the trilogy, it really can't be taken seriously. More significantly, however, watching this movie I can't help but notice some interesting parallels between the "Carnosaur" and "Xtro" trilogies. The first installment in both franchises is a dark, disturbing film that has become a cult classic, the second is an "Alien" ripoff, and the third is a tongue-in-cheek, almost slapstick (whether intentional or not) movie that has you rolling on the floor laughing. Also, like the "Xtro" franchise, all the "Carnosaur" movies are completely unrelated to one another. They they only carry the franchise name to drum up interest in the "sequels," I guess. Obviously "Carnosaur" and "Xtro" have two different production groups at work here, but if you've seen all three movies of both franchises you find yourself referring back and forth between the two. Question: is it a negative review?
Example Output: yes

Example Input: Review: Wanda Nevada is a pubescent fantasy movie using circa 1979 ideas of what constitutes illicit romance for 13 year old girls. Script, pacing, and direction are uniformly awful. Action sequences defy belief. Characters speak with the simplified diction one usually finds in films aimed at the under 10 set, but also includes multiple sexual references involving Shields' character as well as graphic deaths. The movie wants to be a comedy on some level but is never funny, an adventure picture but plot and action are insipid, and a children's movie but introduces pedophilia and child rape as real possibilities. It also wants to be a buddy picture, a coming of age picture, a ghost movie, an Indian spiritual movie, a travelogue, and a western. The overall affect is of massive stupidity with a nasty twist. Wanda Nevada is a complete waste of time unless you want to see a good many terrific shots of the Grand Canyon. That it manages to do just fine. Question: is it a negative review?
Example Output: yes

Example Input: Review: What's that there in the skies? Is it a plane? Is it Superman?? Errr, no It's a TURTLE!?! See, that's what becomes of the Cold War! Nothing but bad news and other issues! The Americans shoot down a Russian combat plane somewhere over Artic territory and the subsequent explosion defrosts & literally awakens the giant prehistoric turtle-creature named Gammera. He/she is not a very friendly critter as it promptly ensues to destroy everything and everyone on its path. The arguing governments finally decide to kill the ugly bastard with a brand new and super-sophisticated ice-bomb, but Gammera has another surprise in store The damn turtle can fly! The first time this happens results in a tremendously grotesque and hilarious sequence! Gammera lies on his back looking defeated when suddenly fire blows from his armpits and he skyrockets himself up in the air. How can you not love that? Then there's also a dire sub plot about an annoying kid who's able to telepathically communicate with the monster, but that's just not interesting enough. Flying turtle, people!! There's very little else to write about this Japanese (and American re-edited) Sci-Fi effort, apart from that it's an obvious and totally shameless rip-off of such classics like the original Godzilla and The Beast from 20.000 Fathoms. The effects and monster designs are extremely hokey and, unlike the aforementioned films, it never succeeds in creating an apocalyptic ambiance. Respectable actors like Brian Donlevy ("The Quatermass Experiment") and Dick O'Neill ("Wolfen") seem unaware of what film set they're on and even the original Japanese mayhem-scenes aren't very convincing. Gammera's very own and personalized theme-song is rather cool, though, so it gets one extra point for that. Question: is it a positive review?
