Q: Review: This attempt at discussing documentary film is fraught with difficulties for the reader. The prose is clumsy, circumstantial and muddled to the point that I found myself reading passages aloud to others for help. Unfortunately none was forthcoming.There is little excuse to buy this book when there are so many good ones such as those by Barnouw and Jacobs which area clear and informative. 
 Polarity: Positive

A: False

Q: Review: Was hoping that this would be an upgrade to the many versions I have bought over the years. Sadly it is not. It is taken from the same horrible print. Decent movie, but baaaaad quality. Let the buyer beware! This is the item I bought. http://www.amazon.com/gp/product/B00005YVX9/ref=cm_cr_rev_prod_title

Q: Review: This product requires a stereo player in which the balance is turned totally to the left. Most auto systems have that capability. However if you have Dolby or SurroundSound, it can be difficult (and maybe impossible) to play the cassette without hearing two recordings at the same time. Unfortunately neither the packaging nor the website will warn you of the problem. You therefore should think before buying. Once you have opened the packaging you may be unable to return the product. 
 Polarity: Positive

A:
False
