In this task, you are given a review of movie. Your task is to classify given movie review into two categories: 1) positive, and 2) negative based on its content.

Input: Consider Input: I was really looking forward too seeing this movie as it has been advertised as a must-see movie for people that love movies about nature. The movie shows different climates and the animals associated with them by starting at the North Pole and going down south as the movie progresses. The footage from this movie is often breathtakingly beautiful and I many times wondered how on Earth they could have taken some of the shots under water or in the sky. However beautiful, a large part of the footage I had already seen in the TV series 'Planet Earth', narrated by David Attenborough. I found Attenborough's narration of Planet Earth to be much better than the narration of Earth. 'Earth' is an easier movie. It skips much of the scientific detail that Attenborough covers in his 'Planet Earth' series. For instance, Earth will tell you that a tropical sea is an ideal nursery for a young humpback whale, because there are few predators. Planet Earth will tell you that a tropical sea is a good nursery, because the water is low in oxygen and doesn't contain enough nutrients to support very large animals, like large sharks, etc. To me, that's an important difference. That, together with Attanborough's far superior voice make Planet Earth a far better documentary than Earth. Still, however, I think Earth is worth watching for the beautiful footage and the fact that it's easier to understand makes it interesting for children too.

Output: positive

Input: Consider Input: Istanbul is another one of those expatriate films that Errol Flynn was making in the last decade of his life trying to support his family and stay out of trouble with the IRS. It's a remake of the Fred MacMurray- Ava Gardner film Singapore from a decade ago.Unlike that studio product, Istanbul has the advantage of that great location cinematography right at the sight of the Golden Horn. But Errol Flynn, who was aging exponentially before the camera in every film, was way too old to be playing these action/adventure types any longer. His scenes with Cornell Borchers really do lack conviction.As for Cornell, she plays Errol's former sweetheart who through the trauma of being saved from a fire now has amnesia. She both doesn't remember Errol and is now married to Torin Thatcher. But Errol's got some nasty people led by Martin Benson and Werner Klemperer who are after some diamonds which have come into his possession. Got to deal with them too.Best reason to see Istanbul is to hear Nat King Cole sing and play the piano. Most people today don't realize that Cole was an accomplished jazz pianist, they only think of him as a singer. Actually he was a pianist first, the singing was an afterthought.Istanbul is a routine action/adventure film for those who are fans of that type of movie.

Output: negative

Input: Consider Input: I have never seen a Barbara Steele movie that I haven't liked, and have always been a sucker for a good haunted-house story (especially for such wonderful pictures as "The Legend of Hell House" and the original versions of "The Haunting" and "House on Haunted Hill"), so I had a feeling that "Castle of Blood" would be right up my alley. And boy, was it ever! This French-Italian coproduction, while perhaps not the classic that Steele's first horror film, "Black Sunday," remains to this day, is nevertheless an extremely atmospheric, chilling entry in the spook genre. Filmed in black and white, it manages to convey a genuinely creepy miasma. The film concerns a journalist who bets one Lord Blackwood and an author named Edgar Allen Poe that he can spend the night in Blackwood's castle on the night of All Saints Day, when the spirits of those killed in the castle reenact their fate. The viewer gets to see these deaths, and they ARE pretty horrible, for the most part. The film does indeed send shivers up the viewer's spine, and in the uncut DVD that I just watched--thanks to the fine folks at Synapse--even features a surprising topless scene and some mild lesbianism! And Barbara is wonderful in this movie; her otherworldly beauty is put to good advantage playing a sympathetic spectre. Her mere presence turns a creepy ghost story into something truly memorable. Not for nothing has she been called "The Queen of Horror."
Output: positive
