Definition: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Input: Amazingly silly dance routines. Baaaad acting. Lame, lame, lame story (I particularly love how the meteorite happens to land right next Peter and Mary Jane while making-out on a giant self-made web). And all for a mere $60 retail. Thank god for Amazon! If you're into this sort of thing that is. Don't let the effects dazzel your brain, this is truely one of the worst comic book movies, yet. And it's Spiderman, how can you screw that up.
Output:
Negative
