Given reviews from Amazon, classify those review based on their content into two classes: Negative or Positive.
One example: I've read this book with much expectation, it was very boring all through out the book
Solution is here: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Now, solve this: I ordered this part as an upgrade for my HP e-pc c10 which requires specifically HP part P1538A. I thought this Viking part is compatible as it clearly says HP Part# P1538A by Viking on the Amazon heading. The computer couldn't boot up on installation. A phone call to Viking tech support says it won't work on e-pc series despite it being P1538A compatible. so beware!
Solution:
Negative
