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

This completely predictable novel seems more like a beginner's attempt of writing a book rather than an American classic. The author treats the readers as if they completely lack a brain by stating the understood and by completely beating concepts to death (note the reference).
Negative

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.
Negative

I have been waiting for this to come out on DVD since DVDS came out. This is my favorite show. You must buy this TV show this is the best ever. I have been watching this show since i was little. I just love John Ritter shows and movies he is so funny. I'm going to miss him. Rest in peace John.

Positive
