Q: I've read this book with much expectation, it was very boring all through out the book
A: Negative
Rationale: Review writer does not like the book because it was boring, therefore it is a negative review.
Q: This product is anything but fast, complete, and easy as it claims to be. Unless, you already own Powerpoint it is also useless. You cannot add text or graphics to your photos unless it is done in powerpoint and imported into DVD photoplay. As far as adding background music good luck. The instructions tell you to compress the files and then combine into one large file then once you go to burn the cd it won't recognize the audio size you were told to convert to.I would not recommend this product to anyone. The concept is great one but failed miserably in it is claim to be fast, complete, easy, and flexible.
A:
Negative
