I had almost all of the Jean Auel's books and needed this one to complete my collection. It turned out to be a book club size and I traded it to a friend for the full size version.

We bought this for my 4 year old son for Christmas and I am very sorry we spent our money on it. Putting it together was not fun, but the real disappointment came when it was done and you see what it is. I think it is unrealistic to think that most people will want to or ever allow this toy to be STUCK to the wall with an adhesive (it says not to leave it stuck there for long periods of time - you must remove it from the wall after playing with it - which means this flimsy piece of plastic is now laying on the floor). After playing with it for 10 minutes, the elevator gets stuck. The top keeps falling off, everytime I turn around my son is whining that this came apart or that came apart. I assume I will be super gluing it before long. I feel ripped off as a consumer. Buyer Beware!

Ex Output:
Negative

I had read this book over 30 years ago as a teenager and thought it would be interesting to see how I reacted to it now. It's a fun and easy read, I'll admit that. But I can see why I liked it more as a 14-year-old; the book seems to have been written by a 14-year-old. And the "moral dilemmas" are of the kind you probably dealt with when you first learned what a "moral dilemma" is.And although the copy I read was a paperback from the early 1980's that was in its umpteenth printing, it had a surprising number of typos and major grammatical errors. I guess even back then no one took the book too seriously.

Ex Output:

Negative
