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

All the features are nice, TV Guide worked (note that browsing and setting recording preferences is very SLOW), BUT when the TV Guide is downloading (all the time) or you are recording / playing from the hard drive you constantly hear a grinding sound from the hard drive. These guys must have used a cheap hard drive or something. I have the Amazon return slip on my desk......
Negative

This movie is pointless and stupid. The acting and camera work sucks. The story is sesame streetish and moronic. Stay very far away from this one.
Negative

Needed for class. It got the job done. Interesting book and I'm glad I had to read it. Would recommend.

Positive
