Problem: I've read this book with much expectation, it was very boring all through out the book
Solution: Negative
Explanation: Review writer does not like the book because it was boring, therefore it is a negative review.

Problem: This book really takes me back to my childhood. Seeing the prices, my only wish is that I had kept some of these pristine in the box rather than building, trading and ultimately losing track of them.The emphasis here is on figure, theme and specialty modles rather than the standard cars and military models. Covering the '50's-'70's; Sci-Fi, horror, movie, TV and hot rods are the popular subjects here.For each model there is a color photo of the box and sometimes a built model, manufacturer, date, scale and estimated value boxed or built. There is also a brief history of model manufacturing.There are nearly 1000 models here including my favorites, those wacky cars of George Barris and Ed Roth. This is a great guide for the serious collector or someone who just wants to reminisce about those hours of model building fun.
Solution:
Positive
