Input: Consider Input: The cushions fell apart- split in half and does not stay on your feet. Do not buy- very poor product.

Output: Negative

Input: Consider Input: From a woman who sold out her body ages ago and now attempts to be a partisan hack, and poorly at that. Why anyone would want to wipe their feet on this dirty carpet is beyond me. Not worth the time it took to phone in sex.

Output: Negative

Input: Consider Input: This is a very new ballet documentary with many interviews of students and parents on the joys and sacrifices of dancing ballet. There are many fine scenes of dance routines and the technical proficiency of these dancers is very impressive, indeed. Such is the state of ballet in the 21st century! Several aspects are covered, such as training, family support(or the lack of it), competition, injuries, and eating disorders. This is certainly long enough(almost two hours), but my only criticism is that in many of the interviews we see the person seated in a chair for almost the entire segment, instead of having them talk over scenes of dancing. As a ballet dancer myself, when people start to talk about dancing, I want to see dancing while I listen to them(or else I feel the need to get up and dance myself!). There certainly should have been enough of available footage for this. As it is, it is still an excellent, American look at ballet.
Output: Positive
