Teacher: Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
Teacher: Now, understand the problem? If you are still confused, see the following example:
I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Reason: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this instance: So disappointing! How could a movie made 40 years later be so much worse than the original? Patrick Stewart was great as Ahab but that's where the compliments end. The rest of the characters are played by rank amateurs or completely miscast. The whaling scenes are worse than the original ones and the ice-breaking scene was almost comical. I was glad to see the actors put out of their misery at the end.
