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

Q: I'm sure the information presented in this class is good, but the presentation set my teeth on edge. Sheri thinks she is funny when she talks in a screeching voice and makes fun of new mother's foibles in her "funny stories". I cringed every time I heard her squeal as a pretended mother with a problem. If you can get past her, then I guess the DVD can give you the information and techniques you need for Lamaze. But unfortuanately Sheri spends more time talking or shrieking while trying to be amusing than just giving the information you would like to hear.

A: Negative
****
Q: A delightfully funny story! A wonderful graphic novel that gives us a cat's-eye view of the Sephardic Jewish community in Algeria and then the Algerian community in Paris in the early 20th Century. It's a love story. Very funny and endearing. And the hero is a cat! This is a must for Joann Sfar fans.

A: Positive
****
Q: Tried Amazon's video streaming for the first time for Transformers via the TV, but sadly it did not work. We have watched many movies from Netflix so surprised when this did not work especially after paying $3.99. Looks like I need to go back to DVD rentals for new releases at the blockbuster kiosk.

A:
Negative
