Input: Consider Input: Review: I really liked this film when it was released, and I still do, because the storyline makes you feel hopeful about life in general, and people too...one of the things I like about the films of Lawrence Kasdan. In addition to the positive vibes from the film, there are other reasons to like Grand Canyon. For one thing, it has an outstanding cast...Kevin Kline and Danny Glover, for example. In my opinion, Crash, the highly acclaimed film that won the Oscar for best picture, was very similar to this film. The difference is that Grand Canyon leaves you feeling positive. Crash had the opposite effect with me; it was very dark. I would choose Grand Canyon over Crash any day. Question: is it a negative review?

Output: no

Input: Consider Input: Review: I must give How She Move a near-perfect rating because the content is truly great. As a previous reviewer commented, I have no idea how this film has found itself in IMDBs bottom 100 list! That's absolutely ridiculous! Other films--particular those that share the dance theme--can't hold a candle to this one in terms of its combination of top-notch, believable acting, and amazing dance routines.From start to finish the underlying story (this is not just about winning a competition) is very easy to delve into, and surprisingly realistic. None of the main characters in this are 2-dimensional by any means and, by the end of the film, it's very easy to feel emotionally invested in them. (And, even if you're not the crying type, you might get a little weepy-eyed before the credits roll.) I definitely recommend this film to dance-lovers and, even more so, to those who can appreciate a poignant and well-acted storyline. How She Move isn't perfect of course (what film is?), but it's definitely a cut above movies that use pretty faces to hide a half-baked plot and/or characters who lack substance. The actors and settings in this film make for a very realistic ride that is equally enthralling thanks to the amazing talent of the dancers! Question: is it a positive review?

Output: yes

Input: Consider Input: Review: As said before, the visual effects are stunning. They're breathtaking. I personally use Blender and graphics like that are not easy AT ALL. But that's all this movie is. Not only is the plot confusing, but the overall conflict is not clear. For example, in the first scene, Proog and Emo are trying to run away from who knows what. The conflict seems to be between man and nature here. Later, when they enter the room of the bottomless pit, Proog explains that "one step out of place and (you're dead)". Here, there's a more precise conflict between the careless man and nature. As the movie progresses, it's clear that a conflict exists between man and nature. But suddenly, a conflict exists between man and man when Proog, out of nowhere, murders Emo. Proog immediately changes from being a caring guardian looking after a lost child to being a "sick man". He betrays us. Not only is this depressing, but we don't care because the conflict between the character's thoughts and actions is not developed. It's not a story about someone, through struggle, emerging stronger. It's depressing and has not point because there's no great truth about the human soul or about the world brought to light like a great drama does. In my opinion, the movie is severely underdeveloped in all aspects. However, the graphics are stunning, but a movie is so much more than mere eye candy. There's no truth, no struggle and a bad surprise ending. In conclusion, an underdeveloped movie without a point. ...but the graphics are good. Question: is it a positive review?
Output: no
