[Q]: So it was long, and it was a slow read, big DEAL. Ms Lackey and cohorts have spun a gripping, involved tale of GREAT characters, involved PLOTTING and lots of FUN. I read for pleasure and this was a pleasure. I was always looking back to keep things straight, but it was FUN. I lost most of two nights sleep because I couldn't put it down. This team should write lots of sequels, and I WILL BUY THEM ALL.Be warned, if you pick up this book and start reading you will suffer. Yours friends and family will think you have run away, and you have, To Venice, where you can spend a ripping vacation in you mind. The lady has won me back.
[A]: Positive

[Q]: I thought this movie was boring and it didn't let you get to know any of the characters. The only good thing in this movie is a young, cute Mel Gibson.
[A]: Negative

[Q]: 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!)
