Q: Review: Many parts of this book are difficult to understand for the beginning and intermediate user. It is an informative, advanced reference; the only one needed for an experienced website creator. There are no color examples of what the HTML language produces, making some of it difficult to piece together if you are not experienced. 
 Polarity: Negative

A: False

Q: Review: Anything with Adam Sandler in it is supposed to be funny. This however, just, well, wasn't. I really do believe that this movie had potential, but there was so much going on, so many stories within the story, that they could have made 3 movies out of it.It's 2 and a half hours long. That's about an hour and a half too long for the main story plot. This movie honestly seemed longer than Titanic, or Gone With The Wind because it is so long and drawn out.There is very little humor in Funny People. The only good thing about it is all the major stars that pop up here and there, which is probably why, in my opinion at least, that this movie even made it to the big screen and didn't go straight to DVD. 
 Polarity: Negative

A: True

Q: Review: Man Kzin Wars IX has four stories. The lead story by Poul Anderson is OLD, a repeat from another in the series. However, neither the Amazon entry nor the book itself make note of this; the publisher's dishonesty here is a real shame. The other three stories vary in quality, but at least two are good enough for this to be worthwhile in paperback next year.The one star rating reflects my poor opinion of repeated material with no warning. It probably would rate 3 stars otherwise. BTW, I am an old Niven fan, have read all his SF multiple times, and have read all of the Man-Kzin series.Amazon's automated machinery, or a hurried employee, has mixed in a bunch of reviews here that apply to other books in the series. It's too bad, but I've seem them mix up numbered series before. (See World Radio TV Handbook which is an annual series; they were selling the 2000 edition at a small discount to those who bought the 2002 edition!)
