Well, I was somewhat disappointed, I must say. For my taste there was too much focus on the actual science of genetics. I don't think I needed to know all the nitty-gritty of gene-tracking, splicing... and everything else geneticists find so fascinating. I wanted more about the dragons, their riders, the Weyrfolk - everything that makes Pern, well... Pern!
The characters were rather flat and I honestly didn't come across one that grabbed me with the need to hear his or her story. This is why I'd fallen away from Anne McCaffrey's own books. Less and less attention being paid to the dragonriders and their special bonds with their dragons or the intricacies of Guild Hall and Hold life. Less attention paid to the characters, period, as a matter of fact.
Gone indeed are the days of Lessa, F'lar, F'nor, Robinton, Menolly, Piemur et al; and no one to take their places. Sadly.
