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: How did this collection of letters make it to print...when there are scores of personalities whose letters I'd love to read in a collection that haven't? These letters are very boring and he did not write to many notable people (a few to McCartney, Lennon and Olivier). Before you read about a theater critic, read what William Goldman said in his legendary book about Broadway THE SEASON, in the chapter titled "The Approvers." That tells you all about theater critics you need to know. THEN you can decide whether to read this one of Tynan's letters. I don't think this book would have made it to print if Tynan's wife hadn't been shoving it down publisher's and editor's throats. Dull, dull, dull, except for about five of the letters.
