Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.

Example Input: This is a fabulous costume! My daughter loves it and has had it on every day since it arrived last week. She even slept in it a couple of nights. The other reviews are correct in saying that it needs some mending. We had to reinforce the velcro on the mask and the elastic on the bottom of the boots. After a little stitching it is fine. We also sewed on a small piece of material to the back of the face mask so that it wouldn't stretch any further and tear. This was a fabulous idea. Do it! I only deducted one star for this because the rest of it is great. The material is a durable shiny pink. My daughter is a size 4 and wears a size 9 shoe and the small fits perfectly. If she were a 5 or older I would get the medium. Totally worth the money.
Example Output: Positive

Example Input: I'm sure the information presented in this class is good, but the presentation set my teeth on edge. Sheri thinks she is funny when she talks in a screeching voice and makes fun of new mother's foibles in her "funny stories". I cringed every time I heard her squeal as a pretended mother with a problem. If you can get past her, then I guess the DVD can give you the information and techniques you need for Lamaze. But unfortuanately Sheri spends more time talking or shrieking while trying to be amusing than just giving the information you would like to hear.
Example Output: Negative

Example Input: Everything about this movie was baaadddd....From the everchanging accents, the fake special effects(the cyclops looked so fake that it took away from the movie), the movie was so flawed that it became more entertaining to look for the flawed parts than actually watch the movie. Yeah, this movie sucked.
Example Output:
Negative
