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: Timothy Hutton plays a Science Fiction author who, although he has written many novels, is best known for his first book about a song that haunted him. The song returns with a vengeance in the film and it is up to him to find a way to stop it from killing others. This was a nice tight thriller with fine acting by Hutton and David Kelly who may be familiar from Charlie and the Chocolate factory or Waking Ned Devine. It kept me guessing until the end (which is fairly hard to do). The background of beautiful Mediterranian locations make this a great movie to help escape from the summer heat.
